My local thrift stores all have piles of old silverplate-no one wants it anymore, and no one wants to polish it,either. I'm always on the hunt for Sterling, and I've found that Sterling items are ALWAYS marked "Sterling" -especially things made in the US. If you are serious about finding Sterling "in the wild", you have to know foreign hallmarks also-they won't say "Sterling" on them, but maybe just a stamped ".925" or something similar. British hallmarks are more involved, but you are always looking for the lion with the raised paw. At every thrift store, I always go through all the silverplate and old silverware-I've found an amazing amount of overlooked Sterling. My most common find are "weighted Sterling" candleholders-I've found dozens of them in the past two years. They are all just a thin skin of silver around a heavy cement or plaster base, but it all adds up.
The little symbol A is a good guide as to the quality of the silver plate. There are tons of different systems and no standard but a century or so ago, many British makers used followed the gradings ... A1 = Superior, A = Standard and then lower and lower grades below that B, C, D, E based on how many pennyweight was plated on. A1 was usually a troy ounce of silver per 12 tablespoons or forks. Also don't get confused with stamped in Old English font which looks like a hallmark. That's electroplated nickel silver and usually pretty thin.
There is a much cheaper way of doing silver plate. The formula is 19 parts sulfuric acid to one part nitric acid. Heat but only to about 140 F. The silver plate will turn white as it dissolves in the solution. When the white is gone, that piece is done. I use three buckets and a plastic colander. I let one batch drain while the next batch is working in the solution. After a batch is drained, I rinse in bucket number one, still in the colander, then bucket number two, then dumped in an empty bucket. Buckets one and two have two gallons of tap water in them. When the solution is spent, it will be very dark and will not take any more silver. I let the solution cool down to ambient temperature. I pour half the solution in each of the water buckets and add a saturated solution of un-iodized saltwater to turn the silver into silver chloride. Work it into silver metal as you wish. You might want to try it in one of your great videos. You do a great job. I enjoy them very much.
Hi frank zahn, my name is Joshua. I processed some e-waste a decent amount of it for gold and I have a lot of the waist but I know there must be silver in. Personally, I think there’s a lot of silver, but I can’t figure out why it won’t precipitate. I don’t know if I neutralized the solution or not so I’m going to try that one more time, but can you give me any advice? I really need help on this because I could use the silver right now. Do you have the time please answer me back. Thank you.
@@sreetips hello sir, my name is Joshua. I asked the same question to the gentleman above. You seem like someone who is busy so I didn’t think to even ask you first. I processed some e-waste a while back, and the waste made a very deep, dark green solution. I know there’s a lot of silver in it but I can’t figure out how to precipitate it out. I have added hydrochloric acid to it. I’ve put copper in the solution hoping to cement it out. Can you please help me?
Mr Sreetips there is a very easy way to de-plate silver. A tub of salt water with a piece of stainless steel for the negative contact and hook the positive contact to the piece of plated silver. Run a current through it for 10-15 min and the silver will flake off
@@lifeindetale I suppose dissolve in nitric and precipitate as AgCl or cement out with copper. In my experience the silver only plates off if you are lucky. It cements back onto the brass, and base metal oxides form at the anode and create a nasty foam. They can be converted to soluble salts by adding HCl, but then chlorine gas evolves at the cathode.
If you undershoot a little bit with the HCl, so you leave just a little silver nitrate in solution. You can filter out your silver chloride, and save the filtrate. You can then use the filtrate to dissolve more silver items, because when you add the HCl you also create nitric acid. You just want to undershoot with the HCl, because if some is left over it will react with the silver and form a AgCl coating keeping the nitric from dissolving it. That way you can save some money on buying more nitric. I actually just did this, it worked out pretty well.
Your videos have gotten much better over the last several years........ This one is new to me, but important for me to learn how much effort I should put into plated vs. sterling pieces.... Thanks
some companies call it Ultraplate, some call it Extraplate. I only found about it awhile back because my grandma had a bunch of it, than I started looking into it. It is very common, mostly older pieces but some newer ones can be found. Yes you can find several pieces with with very thin plating but thick plating isn't rare
Why? The junk silver is worth more than the silver you claim is pure. How can you prove that purity? I know the silver dime is 90% silver and I have a good idea of its weight and value.
@@allenjester3228 not when you call it just. Its worth less. Our testing things as humans have evolved over time. It was once used as currency. You don't think our means of testing is accurate? Do your thing . Do what makes you happy. Life is short.
We’re headed for an economic catastrophe. I’d rather have the constitutional / junk silver than take someone’s word for the value of an item that I don’t recognize. Junk silver has recognizable value. Practice with silver plate or obscure foreign coins and save the junk for us stackers.
@@sreetips not sure if you will get to see my question to you but thought i would try to catch you here. I have some silver electronic wire pieces that dont dissolve in a hour of the acid. Will not turn blue niether in the dissolve state. Only in the copper bath does it turn blue. Any thoughts?
Hello and welcome back :) I'd wish you a happy New Year, but I think it would be nicer to wish you a BETTER year than last year :) And don't think what happened with your stockpot was a disaster...it'll be really exciting and interesting to see how you manage to get all the platinum back. Personally I can't wait to see how you're going to do it :) I'm sure a lot of viewers will agree with me. Thanks for another entertaining video
Problem with nitric its so damn expensive, atleast in 2023... Im not sure about US prices but in the UK its £106 for 5 litres of nitric, if you need to use 800ml to extract 10g of silver then its costing you money. I was thinking about refining karat gold scrap but the cost of the nitric just eats away all the profit plus some more :(
I buy six 2.5 liter bottles for two fifty. Was three hundred with the fifty dollar shipping charge. But last time I ordered, it was still two fifty, but the shipping charge went up to one fifty!
@@sreetips I can see why you only really do karat scrap, anything else is a complete waste of nitric and it appears that refining gold consumes far less nitric than silver.
I finally got the store and I have huge silverware & scrap I gotta go through. It's time for me to learn it now. I told you I'd get that pawn shop in negotiations & now I own it😊
Hey sreetips ! Thank you for all the great content you keep on making ! I have 10kg of silver plated items , it wont make sense to dissolve them in nitric as i will need alot of nitric to do that . I was wondering if sanding the silver off and refining the dust would be a better option ?
I have wondered how using a very course ceramic grit in a vibrating or even in a rotating polishing setup would work. I initially had the idea to strip gold off of pins and fingers etc. as a way to speed up the process by not having to devolve all of the copper
Just as plating I would never have imagined you could get that much silver off of that lid. Understand I dont doubt you a bit as I have learned how sharp you really are at this stuff. Im also extremely jealous at how productive you are and could only hope that I could ever do anything like what you do. I dont like toxic chemicals or agents. I would never work in a trade or plant that would put me anywhere near dangerous lab work. I worked in a production machineshop for just under 28yrs but I would bolt when they had painters painting the floor with very toxic paint. Whenever they painted in that building I bolted to get away. One of the painters never wore a mask I couldnt believe it. You would get a headache right away if you were anywhere near it. Im not exagerating. But you I have learned know exactly what you are doing. Do you have a chemistry degree because you work like a Scientist, I do really enjoy watching what you do and most of all when you end up with an incredible bar of Gold and Silver too. I always wonder if you really should be wearing a good mask or ventilator but I think you know what your doing.
He uses respirators and fume hoods when needed. Chemicals are perfectly safe when handed with safety and respect. No need to " bolt away " just be smart and safe. You sound kind of childish actually
Thank you for taking the time and using your chemicals and shop to show us how to do what you do & now we know to just turn it into a recycling center as the base metal under the silver. ❤❤
I have a question? When you melted your silver cement in the wet filter. Did you use any flux like Borax? I know you glazed you dish before melting? Did you add borax to that silver burn? Streetips your my favorite you tube channel. I have learned so much. Never stop doing your vids. Thxs so much
Holy S.. we got to see sreetips in the 3rd person!! I pictured you so much different. Fantastic! Now I can picture you and Mrs Ips, when you tell stories about where the scrap gold comes from 😄 Did you dye your hair for this.. if not, I'm jealous.
Wondering about sandblasting the silver plate off of the items, then separating the sand and metals with simple tap water and a gold pan. Would allow you to drastically reduce the amount of nitric acid required to pull this off. Could maybe boost the financial feasibility of this specific operation.
I use reverse electroplating to remove silver plate it's actually rather simple to use and drastically reduces the amount of copper contamination to be removed later with the acids (also saves time because the removed silver plate falls off in small thin pieces and copper contaminant is a fine powder that desolves quickly). I use salt water as electrolyte and a car battery charger as a power source...
@Jacob Shrewsbury make sure to check your electroplated solution for silver after u get the silver flakes out, is usually leftover silver suspended in solution u can't see.
We are now in 2023 : and It looks like that value is going up. There are three tangible items that will be worth so much after the dollar collapse. Everything else will be digital currency if we get lucky. Thank you for your demonstration it works for me.
Welcome back. You've bee missed, @Sreetips. I like the addition of the cost vs return calculation in the vids. It's interesting to see the return on investment.
I contacted you on eBay. I have a bulk lot of Silverplate. I can sell the items by the piece, but shipping adds too much cost. Their size and shape make it hard to stuff a priority mail flat rate box full of it. I can deliver if you want it.
How are you doing all the report??? When I pour raw silver, there is no shine, all the tin. I ask you to explain to me, and I wish you all the success in all your work. 🙏✍️
Best to melt into a sheet and electroplate the copper out with copper sulfate and sulfuric acid in a cell will get pure copper and anode slimes being able to reuse the acid many times lowering the acid cost
@@sreetips Great video Sreetips. Glad you are back. :-) Nurd Rage has a video converting copper chloride, from PCB etchant, to copper sulfate then plates out copper to recycle... essentially I would think it's pretty close to the same thing your doing converting the copper & silver nitrate to copper and silver chloride with HCL ... anyway check out the link. th-cam.com/video/FjEoRidvgYE/w-d-xo.html
Look up "growing copper crystals". Electroplating with CuSO4 is actually the industrial process for refining copper. You just need a DC powersupply, a bucket and some CuSO4. Silver won't dissolve in sulfuric acid, but copper will. You're transfering copper from the anode to the kathode, pure silver will collect under the anode, as the copper gets dissolved. Also as you use dichromate for your testingsolution, I've no doubt that you can get CuSO4
I'd say it is a profitable venture seeing where the bidding is, at current time. Quite Profitable if I do say so myself. Great video. Once again you don't disappoint.
Several other items missing from the cost analysis. Not a very cost effective way to obtain silver, but the chemistry was interesting. I am glad YOU did it.
Reed and Barton was (is?) a maker of high quality sterling and silver plate items. They would heavily plate their items-I see some things marked "Quadruple plated" also.
Question??? Why didn't you just use plain non iodine salt in place of the hydrochloric acid to drop the silver out of solution? Is the result different? All your vids get my mind working in over drive .. thank you so much for the education.
Awesome, I’m clumsy so I wouldn’t try my ideas myself. I have a box of gold and silver plated jewelry and some 40%coins I’d like to eventually get the gold silver and copper from. are their trustworthy refiners I could send to that don’t charge an arm and two legs for it. But seriously I pretty much can do it but I’d need instruction step by step on paper just so I don’t miss any steps
Hello, the greatest chemist in the world, thank you for spreading your experience to the viewers. I have an urgent question. I am working on extracting gold from rocks and stones crushed with aqua regia, and I work on large quantities. I have a problem, which is how do I know that the solution is saturated and will not be able to dissolve more gold and I have to replace it? Thank you
Thank you so much for sharing your knowledge, i'm working in a mining lab so we assay gold and silver from ore and pb concetrates. I dissolve the dore button with nitric acid with the purpose to dissolve silver and get a gold button and calculate its content in the samples. I generate a lot of silver nitrate solution every day and I precipitate it with HCl. I will suggest a method based on yours to take benefit of this waste and recover some silver. Greetings from Mexico.
That was pretty interesting street. I recycle off and on and I have about 5 lb of silver plated copper wire. I would like to melt it down and retrieve the silver and copper to recycle the copper as copper 2 and take the silver to a jewelry store and get paid for the silver. Anyway of just melting it down on the store or with a propane torch? I'm not much into using chemicals.
First time watching! Stumbled upon video while researching Büchner funnel uses. I have a bunch of those Büchner funnels. Are they worth waiting to sell to people on eBay?
EDIT!!! EDIT!! EDIT!! HAHAHA! I see you DID mention it at the beginning of the video. Disregard my aforementioned statement. :D You forgot to mention the nitrogen dioxide danger this time. :D I've watched other videos you've made where you did mention the danger so that's how I know you forgot. Love your videos. You are so meticulous I thought for certain you had a background in chemistry. I was surprised to learn that you're a hobbyist! Nice job at being so efficient. I'm a jeweler so that's why I have an interest in precious metals recovery. :)
the best way to test silver is with 18k test acid. and a super tiny drill bit you can find them in beuty stores they use then for finger nails. you just find a spot drill in past the plated test with the acid if it turns green its plated. then after that spot can be fixed buy a buffing pad if the person wants to repair the peace.
If you knew the base metal was copper you could etch it out with cupric chloride or ferric chloride which is a lot cheaper than nitric. Ferric would also dissolve brass base metals. Or would that not work due to contaminants or unwanted metals like iron, tin, zinc? Probably have to cut it into smaller pieces to expose more base metal because those solutions are not as aggressive as nitric.
@@sreetips My electronics hobby, we use cupric chloride and /or ferric chloride to etch copper off printed circuit boards, ferric will also etch brass. I was just thinking those might works for dissolving out copper and brass plus they are a lot cheaper than Nitric.
Of course ferric chloride works work, but it would take quite some time. The benefit is the obvious fact that no workup is required after the dissolution step; just rince the silver and you're good to go!
@@glennbartusch7310 With all the stuff Sreetips has laying around and tied up in waste solutions, I don't think that letting it sit around for the time it would take to dissolve the copper would bother him much. However the process might not work on high percentage alloys for the same reason that you have to inquart some gold alloys.
The stock pot end was sadder then the last scene of "Old Yeller", I am putting together a small plating shop to do as a hobby, zinc, copper, nickel etc mainly automotive and motorcycle parts and came across one of your videos, needless to say i have been binge watching since. What is the possibility of making gold plating solution for electroplating emblems on cars ect. I see the are getting 180.00 per quart shipped containing 1 DWT, pennyweight of 24k fine gold in one of the listings on ebay. I have seen that there is a process using potassium ferricyanide and gold chloride. Thank you for your videos and you have a new fan.
I really enjoyed this video and learning more about silver plate. I was surprised by the amount at the end. I also really liked going through the costs and seeing that it is not worth it to separate it. I wonder also though about how much the copper is worth that was in it. 😀😀
Having your wife showing some of her shopping trips with hints would be great. The secret to making this a profitable hobby is a good, steady source of reasonably priced raw materials.
"Thick" silver plate is often silver "clad" rather than plate. This is done when the flat sheet of metal is made, already clad in the silver then it stamped out and presses into shape.
Hi Sreetips, I am a new watcher and you have me hooked. QUESTION: what is the orange gas and would it make the reaction and therefore nitric acid use more efficient if a condenser was used to drop it back into the beaker?
Experiment was not for the production of... Or the extraction of silver. This was just a good experiment. Had this been an ACTUAL ATTEMPT at recovering sliver... A lot more. A LOT MORE plated or any particular products you want to place in the beaker. In order to recover higher amounts of silver concentrate. Would have been added !
Thanks for the breakdown at the end. What about the sodium hydroxide $ what is your time worth and what is the Map gas for melting it down cost $$ all is overhead. so to me, it looks like you might break even at best. Is it any cheaper to just smelt it down from the start ?
Ya I got that, I just been looking at doing this sort of thing but don't want to do it and not at least come out a bit ahead. Thanks for the reply.@@sreetips
I see. The only reason I did this was because I seen how thick the silver coating was over the base metal. Most silver plated stuff is not that thick. This item was unusually thick, and that’s why I choose to do it.
I collect scrap Sterling and a bit of Silverplate, there are definitely different thicknesses of plated silver items, some even say triple plate on them not that that means much. On the profit side of things, I find that collecting and reselling sterling silver rings and things or even plated items as the item itself has a higher profit than smelting or chemical refining. So then I buy a high-quality 999. Silver rounds or bullion, it is a better bet. Well as long as you are having Fun that's what it is about.@@sreetips
Lol ok I'm requesting you try a few pounds of thinly gold plated costume jewelry at the other end of spectrum 0.1%? It can't be as costly as that eBay bar video! Cheers
like your video. think I would take an angle grinder to that plate inside your containment box and remove all the silver that way then sweep it all into beaker that would eliminate having to dissolve everything and yield per acid used would be much higher
I tried using a Sliver Cell setup to strip Silver plate from objects like that. I used Potassium Nitrate as the electrolyte. It seems to work. Pretty quickly too.
i send you the formula and the steps to operate the bath if you like... so you can tray it in small scale to anderstand the process its very economical and kwicly done.
OK, some questions and comments. 1) I saw another video where the guy just used salt, water and a battery charger. What's the difference? 2) You never explained how to safely dispose of all those toxic acids. 3) Copper is recyclable too. Is there a way to separate the silver from the copper and save both for reprocrssing?
Thanks for your great Video, very instructional as always ! One question, It´s possible to "UnPlate" the item, that is, using the appropriate electrolyte can electrically remove the thin layer of silver ? Maybe this way is economically feasible.
I am gururaj you are using how many liter corningware same I want to buy . please reply me . this same silver procedure I followed I got success 5 grms is my result . first learned in my country India while doing so many confusion for me then I started watching your video simple and easy
Nice video and great way to get pure silver but I have about 100 pieces of silver plated flatware and 20 or so silver plated platters and I am looking for an easier and more economical way to get the silver out of all that. I am pretty sure most of it has a thinner plating than your platter did so I believe nitric acid will just cost too much. Have any ideas that will not require days of labor or cost more than the silver is worth? Have a wonderful day.
Scott, this is my first try with silver plated scrap. Maybe when silver gets to $100 per ounce then it will become viable to use nitric to get it off of silver plated items. For now, I don't know any other ways of getting the silver - yet.
I've seen 2 or 3 people on TH-cam do it with electrolysis and it looks pretty easy. Here's a video from Moose Scrapper: th-cam.com/video/H_LbT3mhilI/w-d-xo.html
Great to see you back bud. I have done a lot of checking on this project. Is it really worth all the process ? I guess the end numbers say it all eh. It will be neat to see the end results my friend. Your chemistry is to be admired my friend.
Wish I would have found this video before I started buying silver. I have about 70 utensils that only 20 or so are not silver plated. Luckily I didn't offer much money for all of it, but I doubt I turn a profit if I refine it. Maybe it's still worth using the plated items to inquart my gold, but I'm not sure what the base metals are on some. One piece I cut up looks like a silver colored metal that turns green with silver test acid. Funny thing is every one of these pieces tested positive for silver because I didn't want to file into them before I bought them. Lesson learned! I'm not buying anymore silver unless it is stamped sterling!
Zeke, about 5% of silver jewelry marked 925 is not silver. Test each piece with schwerters. Putting schwerters on silver plated will test positive for silver. Got to go down into the metal with a file. It’s the only way, at our level, to be sure.
@@sreetips thank you. I was thinking about integrating a specific gravity test into my tests because some people obviously don't want me to file into there stuff before I buy it. Moving forward I will insist on them letting me or pass on the purchase. Honestly it seems silver plated material is everywhere and sterling is more rare than karat gold
For those I ask them if they want to know if it real. If it is then the test will reveal it and I buy the piece. If it’s not real, say silver over brass, then it’s almost worthless. If they refuse, then I walk away. A guy tried to sell me a gold bar in plastic. Before I buy I must take it out and test it. He refused so I handed it back and walked away. If they really want to sell then the test shouldn’t matter.
@@sreetips I'm thinking I might use sodium sulphite in a stripping cell to get the silver plate off. It is cheap and I would rather get what silver I can off for inquarting. The silver will use less nitric acid than copper or other base metals from what I'm reading.
Is there a profitavle way to process silverplate?If u include ur time its a real waste to me..Thanks for the videos I do enjoy ur process of neatness and efficientcy,your one of the best.
As long as they can print money, metal prices will remain low because they can (and do) use paper silver contracts to reduce the spot price, and therefore the demand, for physical metals. They use inflation (money printing) to kill the inflation hedge. It’s brilliant. And it works. So if your point of view is: recover the metal, sell the recovered metal to cover the cost, and end up with a “profit” then forget it. However, if you don’t have to sell the metal once you recover it, then your profit is the metal that you recover, then expense doesn’t matter.
@@sreetipsso, if I was to collect plated pieces found at garage sales and thrift stores, I could slowly add to my silver stack? I saw a site where you could send items for retirement, wondering if that is worth it.
@@JeffJones72 I've had much better luck at estate sales than at garage sales. I've sporadically had great finds at thrift stores. Always look for the opportunity. Regarding investing for retirement, look into opening a Roth IRA. It's funded by after-tax dollars, investments grow (ideally), and the profits can be withdrawn tax-free after 59 and half. Canada has a tax treaty with the USA and won't tax dividends on Canadian companies held within a Roth IRA. Many of the best mining companies are domiciled in Canada. For example -- Wheaton Precious Metals, Franco-Nevada, Barrick, Agnico Eagle, B2Gold, First Majestic, Kinross, Osisko, and many others. 👍 🍻
What happened to using sulfuric acid as a cheaper way of de solving silver? I understand that using nitric acid is quicker but can't make profit if using that method! I hope you can share a more cost effective way of refining silver. Thank you for all the hard work you put in to making these videos!!
So I'm working on some silverware and silver plated dishes, could you please make that video about the same stuff. I'm having trouble de solving the silverware, lol! It's taking longer than I thought and I have alot of it!! Also if you know a safe and easy way of cutting the dishes and trays, thank you!!
Silver plated is very low silver content. I’ve got a bin full of it that I’m saving. Sulfuric on silver plate is something that I’ve never done. No experience there.
Is my math off, or did it cost almost double the value of what was recovered? How to overcome this? Cheaper chemicals? Very insightful video, thanks for sharing your knowledge.
Ok if you use the Nitrect and distilled water 3/1 three parts water and one part acid completely covering the plated metal, no heat is NESARY with this method after about 30 minutes or when the saloution stops bubbling strain the saloution so there is no meatle, use unionized table salt adding slowly, when the salt stops dissolving and there is what looks like cottage cheese strain off all liqewed prince with clean water. The remaining is or should be 99.9 silver chloride. Total prosec should take two hours. And be safe use rubber gloves and eye protection do this outside avoid breathing any fumes are poision to the body.
I had about 1.5 liters of distilled water. 900ml nitric acid. With no heat it would take days to get everything in solution. I've got another silver plated platter. I'll do another video with no heat so we can see how long it will take to get all the copper dissolved. I'm guessing four or five days at least.
wow, that was very interesting. thank you for that. now I don't know much about everything you were doing, but I was following u. to my lay understanding. all metals of the periodic table are soluable? is that true or then my spelling.😁
Robert, nitric will dissolve silver, copper, brass, zinc. But nitric won't dissolve gold, platinum, aluminum or stainless steel. Some metals are soluble in certain acids but insoluble in others. We can use this knowledge to selectively separate metals from each other.
What about extracting the gold from mineralized outcrops? Like say malichite and chrysicola to get the copper out, or silver from pyrargynite? Is there a way to get the gold out of the pyrite. I have a indigo blue metal with gold veins and pyrite in it that sets my metal detector off that has copper and iron keyed out so it dont read them. I want the gold out.
Is it worth the effort to recover the silver plate from the back of 24" x 30" old mirror? The silver is coated with a layer of black paint. It's water damaged, so the silver peels right off glass.
HI! I have a problem about silver recovery from silverplated silverware. The basic metal is zinc, then a thin layer of copper and then silverplating on. First i try to disolve whole spoon in nitric acid, but it starts to boil over the floor. I repead the proces with less concetrated nitric acid, the spoon is disolved, but i have a lot of powder on bottom, the liquid is blueish. So im guesing that zinc is on the bottom like powder, silver is in liquid? or did zinc something else to my silver? Now I will first melt the zinc away and scrap the upper layer down, and i will procced with that nugget forward
Zinc is soluble in nitric acid it will turn your solution green. Get a small sample of the blue liquid and test it with a few drops of hydrochloric acid like I did in the video. What ever is on the bottom, it shouldn't be zinc. It might be your silver.
@@sreetips Hi again. I finished disolving silverplated silverware in nitric acid, filtered it and put Hcl and nothing happened. Like no silver inside. No cloudiness... ;( Should I try put copper inside to cement silver? But now I have second problem with recovering gold from cpu...I disolved 15cpu and few ram sticks in Hcl + hidrogen perokside (little), put those goldplating leaves in aqua regia, they disolved, filtered the liquid and today I got my smb by mail, (in Slovenia hard to buy), and surprise...nothing happened with liquid..like no mud at the bottom, still green yelowish colour...I put it so much that smb sit on the bottom...no reaction. Do you know what could go wrong? Should I put a little bit of urea inside?
Would it be more economically feasible to reverse electroplate the plated material instead of dissolving everything? Say like you had a good amount of plated silver utensils?
Would it be possible to rinse the plated items with acid removing the upper layer until all of the silver is dissolved and then discard or scrap the brass/copper base metal? That would reduce the amount of acid consumed.
Very interesting video. Calculating the silver price would need to be $30.40 or higher to be worth your while but including time probably $50 or higher. That's expensive! Is there a less costly way to do it? Chemical prices are also probably higher today.

There is a much cheaper way of doing silver plate. The formula is 19 parts sulfuric acid to one part nitric acid. Heat but only to about 140 F. The silver plate will turn white as it dissolves in the solution. When the white is gone, that piece is done. I use three buckets and a plastic colander. I let one batch drain while the next batch is working in the solution. After a batch is drained, I rinse in bucket number one, still in the colander, then bucket number two, then dumped in an empty bucket. Buckets one and two have two gallons of tap water in them. When the solution is spent, it will be very dark and will not take any more silver. I let the solution cool down to ambient temperature. I pour half the solution in each of the water buckets and add a saturated solution of un-iodized saltwater to turn the silver into silver chloride. Work it into silver metal as you wish. You might want to try it in one of your great videos. You do a great job. I enjoy them very much.
Frank, I printed this comment for future reference. I may try this later on. Thank you for the suggestion.

I would love to see the process used.
Hi frank zahn, my name is Joshua. I processed some e-waste a decent amount of it for gold and I have a lot of the waist but I know there must be silver in. Personally, I think there’s a lot of silver, but I can’t figure out why it won’t precipitate. I don’t know if I neutralized the solution or not so I’m going to try that one more time, but can you give me any advice? I really need help on this because I could use the silver right now. Do you have the time please answer me back. Thank you.
@@sreetips hello sir, my name is Joshua. I asked the same question to the gentleman above. You seem like someone who is busy so I didn’t think to even ask you first. I processed some e-waste a while back, and the waste made a very deep, dark green solution. I know there’s a lot of silver in it but I can’t figure out how to precipitate it out. I have added hydrochloric acid to it. I’ve put copper in the solution hoping to cement it out. Can you please help me?
Mr Sreetips there is a very easy way to de-plate silver. A tub of salt water with a piece of stainless steel for the negative contact and hook the positive contact to the piece of plated silver. Run a current through it for 10-15 min and the silver will flake off
Then what?
@@lifeindetale I suppose dissolve in nitric and precipitate as AgCl or cement out with copper. In my experience the silver only plates off if you are lucky. It cements back onto the brass, and base metal oxides form at the anode and create a nasty foam. They can be converted to soluble salts by adding HCl, but then chlorine gas evolves at the cathode.
If you undershoot a little bit with the HCl, so you leave just a little silver nitrate in solution. You can filter out your silver chloride, and save the filtrate. You can then use the filtrate to dissolve more silver items, because when you add the HCl you also create nitric acid. You just want to undershoot with the HCl, because if some is left over it will react with the silver and form a AgCl coating keeping the nitric from dissolving it. That way you can save some money on buying more nitric. I actually just did this, it worked out pretty well.
Your videos have gotten much better over the last several years........ This one is new to me, but important for me to learn how much effort I should put into plated vs. sterling pieces.... Thanks
Glad to see you back. Was worried that the little fiasco sapped your will to make videos. Keep them coming.

I think of him as the Walter White of home refining....LOL!
some companies call it Ultraplate, some call it Extraplate. I only found about it awhile back because my grandma had a bunch of it, than I started looking into it. It is very common, mostly older pieces but some newer ones can be found. Yes you can find several pieces with with very thin plating but thick plating isn't rare
I started buying junk silver from my area. I cant wait to try to do some refining.
Why? The junk silver is worth more than the silver you claim is pure. How can you prove that purity? I know the silver dime is 90% silver and I have a good idea of its weight and value.
@@allenjester3228 not when you call it just. Its worth less. Our testing things as humans have evolved over time. It was once used as currency. You don't think our means of testing is accurate? Do your thing . Do what makes you happy. Life is short.

Problem with nitric its so damn expensive, atleast in 2023... Im not sure about US prices but in the UK its £106 for 5 litres of nitric, if you need to use 800ml to extract 10g of silver then its costing you money. I was thinking about refining karat gold scrap but the cost of the nitric just eats away all the profit plus some more :(
I buy six 2.5 liter bottles for two fifty. Was three hundred with the fifty dollar shipping charge. But last time I ordered, it was still two fifty, but the shipping charge went up to one fifty!
@@sreetips I can see why you only really do karat scrap, anything else is a complete waste of nitric and it appears that refining gold consumes far less nitric than silver.
Thank you for sharing your calculation and satisfy my curiosity about the costs!
I finally got the store and I have huge silverware & scrap I gotta go through. It's time for me to learn it now. I told you I'd get that pawn shop in negotiations & now I own it😊
Nice! Treat your customers right and you’ll do fantastic.
Hey sreetips ! Thank you for all the great content you keep on making !
I have 10kg of silver plated items , it wont make sense to dissolve them in nitric as i will need alot of nitric to do that . I was wondering if sanding the silver off and refining the dust would be a better option ?
Good thought that way you would need much less nitric acid. Flat areas would be easier, relief areas would be tough.. Good idea though.

I have wondered how using a very course ceramic grit in a vibrating or even in a rotating polishing setup would work.
I initially had the idea to strip gold off of pins and fingers etc. as a way to speed up the process by not having to devolve all of the copper

Yay you're back! I was worried about your wrists at times with that platinum.
Just as plating I would never have imagined you could get that much silver off of that lid. Understand I dont doubt you a bit as I have learned how sharp you really are at this stuff. Im also extremely jealous at how productive you are and could only hope that I could ever do anything like what you do. I dont like toxic chemicals or agents. I would never work in a trade or plant that would put me anywhere near dangerous lab work. I worked in a production machineshop for just under 28yrs but I would bolt when they had painters painting the floor with very toxic paint. Whenever they painted in that building I bolted to get away. One of the painters never wore a mask I couldnt believe it. You would get a headache right away if you were anywhere near it. Im not exagerating. But you I have learned know exactly what you are doing. Do you have a chemistry degree because you work like a Scientist, I do really enjoy watching what you do and most of all when you end up with an incredible bar of Gold and Silver too. I always wonder if you really should be wearing a good mask or ventilator but I think you know what your doing.
My degree is in Aviation. I’m a retired Naval Engineer. I get whiffs of fumes every now and then. SO2 gas is the worst for me.
He uses respirators and fume hoods when needed. Chemicals are perfectly safe when handed with safety and respect. No need to " bolt away " just be smart and safe. You sound kind of childish actually
Thank you for taking the time and using your chemicals and shop to show us how to do what you do & now we know to just turn it into a recycling center as the base metal under the silver. ❤❤
I have a question? When you melted your silver cement in the wet filter. Did you use any flux like Borax? I know you glazed you dish before melting? Did you add borax to that silver burn? Streetips your my favorite you tube channel. I have learned so much. Never stop doing your vids. Thxs so much
I don’t think I did. But if I did it was very small amounts only
glad your back, was concerned you stopped doing videos or something, keep up the good work!

Oh hell, this is 5 yrs old!?
FYI, I'm a future follower 3 1/2 years from when this was shot.
This was fun to watch but from a personal point of view, I believe the dish was more valuable as an attractive silver plate. Thanks.
It was a good looking dish, with an unusually thick coating of silver.
Wondering about sandblasting the silver plate off of the items, then separating the sand and metals with simple tap water and a gold pan. Would allow you to drastically reduce the amount of nitric acid required to pull this off. Could maybe boost the financial feasibility of this specific operation.
I use reverse electroplating to remove silver plate it's actually rather simple to use and drastically reduces the amount of copper contamination to be removed later with the acids (also saves time because the removed silver plate falls off in small thin pieces and copper contaminant is a fine powder that desolves quickly). I use salt water as electrolyte and a car battery charger as a power source...
@Jacob Shrewsbury make sure to check your electroplated solution for silver after u get the silver flakes out, is usually leftover silver suspended in solution u can't see.
We are now in 2023 : and It looks like that value is going up. There are three tangible items that will be worth so much after the dollar collapse. Everything else will be digital currency if we get lucky. Thank you for your demonstration it works for me.

Welcome back. You've bee missed, @Sreetips.
I like the addition of the cost vs return calculation in the vids. It's interesting to see the return on investment.

I contacted you on eBay. I have a bulk lot of Silverplate. I can sell the items by the piece, but shipping adds too much cost. Their size and shape make it hard to stuff a priority mail flat rate box full of it.
I can deliver if you want it.
How are you doing all the report??? When I pour raw silver, there is no shine, all the tin. I ask you to explain to me, and I wish you all the success in all your work. 🙏✍️
Sorry, I don’t understand your question
Best to melt into a sheet and electroplate the copper out with copper sulfate and sulfuric acid in a cell will get pure copper and anode slimes being able to reuse the acid many times lowering the acid cost
I don't have any experience with that. Can you make a video and show how it's done? Thanks for watching.
sodium sulphite is even better, non-toxic, cheap alternative.
@@sreetips Great video Sreetips. Glad you are back. :-) Nurd Rage has a video converting copper chloride, from PCB
etchant, to copper sulfate then plates out copper to recycle... essentially I would think it's pretty close to the same thing your doing converting the copper & silver nitrate to copper and silver chloride with HCL ... anyway check out the link. th-cam.com/video/FjEoRidvgYE/w-d-xo.html
Look up "growing copper crystals". Electroplating with CuSO4 is actually the industrial process for refining copper. You just need a DC powersupply, a bucket and some CuSO4. Silver won't dissolve in sulfuric acid, but copper will. You're transfering copper from the anode to the kathode, pure silver will collect under the anode, as the copper gets dissolved. Also as you use dichromate for your testingsolution, I've no doubt that you can get CuSO4
Watching this now shows how much your processes have changed in the last few years.
I'd say it is a profitable venture seeing where the bidding is, at current time. Quite Profitable if I do say so myself. Great video. Once again you don't disappoint.
Great to see you back again! I was hoping that the stock pot refining disaster did not take the wind out of your sails for continuing your videos.
Mike. I'm going to process all the paper from the mess I made. Should be several hundred dollars worth of metal.
Several other items missing from the cost analysis. Not a very cost effective way to obtain silver, but the chemistry was interesting. I am glad YOU did it.
Me too
Reed and Barton was (is?) a maker of high quality sterling and silver plate items. They would heavily plate their items-I see some things marked "Quadruple plated" also.
Question??? Why didn't you just use plain non iodine salt in place of the hydrochloric acid to drop the silver out of solution? Is the result different? All your vids get my mind working in over drive .. thank you so much for the education.
Plain salt can be used. I have plenty of hydrochloric acid and I like the convenience of just pouring it in.
Awesome, I’m clumsy so I wouldn’t try my ideas myself. I have a box of gold and silver plated jewelry and some 40%coins I’d like to eventually get the gold silver and copper from. are their trustworthy refiners I could send to that don’t charge an arm and two legs for it.
But seriously I pretty much can do it but I’d need instruction step by step on paper just so I don’t miss any steps
I just sell my silver plated trays and such to my refiner for $1.75 per pound. Works for me.
FYI sulphuric acid stripping cell better way to go.
Yeah or salt water. Seems a waste of Nitric Acid
Glad you're back, thanks for the vid!
You might want to look into the value of that cookware you're using. Those old floral decorated Corning dishes are going for a bit of money.
Hello, the greatest chemist in the world, thank you for spreading your experience to the viewers. I have an urgent question. I am working on extracting gold from rocks and stones crushed with aqua regia, and I work on large quantities. I have a problem, which is how do I know that the solution is saturated and will not be able to dissolve more gold and I have to replace it? Thank you
Extracting gold from crushed rock is not something I have experience with.
Alright, here we go again. When you get to the end, please be careful and don't spill it all. Thanks for coming back to teach us
In your experience, what is the range of silver to total metal? It was 4.6% here but what is the general range? Thanks!
Thank you so much for sharing your knowledge, i'm working in a mining lab so we assay gold and silver from ore and pb concetrates. I dissolve the dore button with nitric acid with the purpose to dissolve silver and get a gold button and calculate its content in the samples. I generate a lot of silver nitrate solution every day and I precipitate it with HCl. I will suggest a method based on yours to take benefit of this waste and recover some silver. Greetings from Mexico.
Nice, glad you gained something. Thank you.
That was pretty interesting street. I recycle off and on and I have about 5 lb of silver plated copper wire. I would like to melt it down and retrieve the silver and copper to recycle the copper as copper 2 and take the silver to a jewelry store and get paid for the silver. Anyway of just melting it down on the store or with a propane torch? I'm not much into using chemicals.
If you melt the wire then the metals will alloy together.
No commercials, I subscribed. love your videos!

@@shortsenstuff I’ll send some pictures after work. How many do you need?
In the UK most silver plated items have the "EPNS" stamped on them. This stands for Electro Plated Nickel Silver.
Ive seen it. I look for EP (electroplated) but I can also tell by the texture of the surface.
EDIT!!! EDIT!! EDIT!! HAHAHA! I see you DID mention it at the beginning of the video. Disregard my aforementioned statement. :D
You forgot to mention the nitrogen dioxide danger this time. :D I've watched other videos you've made where you did mention the danger so that's how I know you forgot. Love your videos.

I'm a jeweler so that's why I have an interest in precious metals recovery. :)
I don’t know about you guys but that blue liquid looks like it tastes delicious.
the best way to test silver is with 18k test acid. and a super tiny drill bit you can find them in beuty stores they use then for finger nails. you just find a spot drill in past the plated test with the acid if it turns green its plated. then after that spot can be fixed buy a buffing pad if the person wants to repair the peace.
I prefer a file and schwerter's solution. Fast and easy
If you knew the base metal was copper you could etch it out with cupric chloride or ferric chloride which is a lot cheaper than nitric.
Ferric would also dissolve brass base metals.
Or would that not work due to contaminants or unwanted metals like iron, tin, zinc?
Probably have to cut it into smaller pieces to expose more base metal because those solutions are not as aggressive as nitric.
I’ve never worked with those
@@sreetips My electronics hobby, we use cupric chloride and /or ferric chloride to etch copper off printed circuit boards, ferric will also etch brass.
I was just thinking those might works for dissolving out copper and brass plus they are a lot cheaper than Nitric.
Of course ferric chloride works work, but it would take quite some time. The benefit is the obvious fact that no workup is required after the dissolution step; just rince the silver and you're good to go!
@@glennbartusch7310 With all the stuff Sreetips has laying around and tied up in waste solutions, I don't think that letting it sit around for the time it would take to dissolve the copper would bother him much.
However the process might not work on high percentage alloys for the same reason that you have to inquart some gold alloys.
The stock pot end was sadder then the last scene of "Old Yeller", I am putting together a small plating shop to do as a hobby, zinc, copper, nickel etc mainly automotive and motorcycle parts and came across one of your videos, needless to say i have been binge watching since. What is the possibility of making gold plating solution for electroplating emblems on cars ect. I see the are getting 180.00 per quart shipped containing 1 DWT, pennyweight of 24k fine gold in one of the listings on ebay. I have seen that there is a process using potassium ferricyanide and gold chloride. Thank you for your videos and you have a new fan.
I'll have to do some research on gold plating solution. Sounds like a good topic for a new video. Thank you.
Welcome back sreetips! I have been waiting for new video... Also looking forward to see new videos in future. Especially platinum refining.
Coming very soon, thank you
Thank you for this video very informative. I am interested to know what the copper solution is. Is it copper oxicloride?
The blue liquid is copper nitrate.
I really enjoyed this video and learning more about silver plate. I was surprised by the amount at the end. I also really liked going through the costs and seeing that it is not worth it to separate it. I wonder also though about how much the copper is worth that was in it. 😀😀
Having your wife showing some of her shopping trips with hints would be great. The secret to making this a profitable hobby is a good, steady source of reasonably priced raw materials.
I agree - would make killer videos.
"Thick" silver plate is often silver "clad" rather than plate. This is done when the flat sheet of metal is made, already clad in the silver then it stamped out and presses into shape.
Glad to see you back.
That last video was devastating.
I'm going to get some metal from that paper and cardboard. Watch for the video.

We are all looking forward to seeing that.
This is absolutely one of the best science channels on TH-cam.
Great video!!! When does adding borax make sense in process like this?
I add borax to the melt dish to keep the silver from sticking to the dish
Hi Sreetips, I am a new watcher and you have me hooked. QUESTION: what is the orange gas and would it make the reaction and therefore nitric acid use more efficient if a condenser was used to drop it back into the beaker?
Orange gas = nitrogen dioxide. Refluxing it would improve efficiency.
Experiment was not for the production of... Or the extraction of silver.
This was just a good experiment.
Had this been an ACTUAL ATTEMPT at recovering sliver... A lot more.
A LOT MORE plated or any particular products you want to place in the beaker. In order to recover higher amounts of silver concentrate.
Would have been added !
Usually plated will have an “A” or “community plate”
Thanks for the breakdown at the end. What about the sodium hydroxide $ what is your time worth and what is the Map gas for melting it down cost $$ all is overhead. so to me, it looks like you might break even at best. Is it any cheaper to just smelt it down from the start ?
It’s my hobby. I don’t keep track of expenses for each batch.
Ya I got that, I just been looking at doing this sort of thing but don't want to do it and not at least come out a bit ahead. Thanks for the reply.@@sreetips
I see. The only reason I did this was because I seen how thick the silver coating was over the base metal. Most silver plated stuff is not that thick. This item was unusually thick, and that’s why I choose to do it.
I collect scrap Sterling and a bit of Silverplate, there are definitely different thicknesses of plated silver items, some even say triple plate on them not that that means much. On the profit side of things, I find that collecting and reselling sterling silver rings and things or even plated items as the item itself has a higher profit than smelting or chemical refining. So then I buy a high-quality 999. Silver rounds or bullion, it is a better bet. Well as long as you are having Fun that's what it is about.@@sreetips
I would be interested to see if you get a similar yield on some other examples. Might be alot of variation? Love it thanks,!
The only reason I did this one is because I noticed it had an extra thick coating of silver.
Lol ok I'm requesting you try a few pounds of thinly gold plated costume jewelry at the other end of spectrum 0.1%? It can't be as costly as that eBay bar video! Cheers
Gold plated costume jewelry has just a few microns of gold over junk pot metal. Almost nothing. I’d end up with a toxic mess and no gold.
Thank you for this. I am looking at silver recovery and now know on cost yield ratio
You didn't filter the test tube contents before pouring into the filtered solution. So it could be slightl impurities in the melted chunk...
Fascinating!
It seems you forgot to factor in the purchase price of the plate - $5, cheers.
like your video. think I would take an angle grinder to that plate inside your containment box and remove all the silver that way then sweep it all into beaker that would eliminate having to dissolve everything and yield per acid used would be much higher
Kirt, I'd rather let the chemicals do all that work for me.
Great video +Sreetips, enjoyed this as always!
I tried using a Sliver Cell setup to strip Silver plate from objects like that. I used Potassium Nitrate as the electrolyte. It seems to work. Pretty quickly too.
only potassium nitrate no acid in the electrolyte...
I’d like to try it.
i send you the formula and the steps to operate the bath if you like... so you can tray it in small scale to anderstand the process its very economical and kwicly done.
OK, some questions and comments.
1) I saw another video where the guy just used salt, water and a battery charger. What's the difference?
2) You never explained how to safely dispose of all those toxic acids.
3) Copper is recyclable too. Is there a way to separate the silver from the copper and save both for reprocrssing?
1) not sure 2) waste treatment 3) to a refiner, copper is waste
reprocessing?, one more question. Can the same process be used with gold plate? Or like separating gold fill?
No, gold plated is best processed in a sulfuric acid stripping cell.
Thanks for your great Video, very instructional as always ! One question, It´s possible to "UnPlate" the item, that is, using the appropriate electrolyte can electrically remove the thin layer of silver ? Maybe this way is economically feasible.
Yes it is, there are a few people who've posted videos on this :)!
There is a way to do it, but I’ve not mastered it. Maybe when silver gets up around a hundred bucks.
the base material, commonly brass, has also some scrap value.
I am gururaj you are using how many liter corningware same I want to buy . please reply me . this same silver procedure I followed I got success 5 grms is my result . first learned in my country India while doing so many confusion for me then I started watching your video simple and easy
Now I wanted to learn mlcc from e weast how to contact you

Nice video and great way to get pure silver but I have about 100 pieces of silver plated flatware and 20 or so silver plated platters and I am looking for an easier and more economical way to get the silver out of all that. I am pretty sure most of it has a thinner plating than your platter did so I believe nitric acid will just cost too much. Have any ideas that will not require days of labor or cost more than the silver is worth? Have a wonderful day.
Scott, this is my first try with silver plated scrap. Maybe when silver gets to $100 per ounce then it will become viable to use nitric to get it off of silver plated items. For now, I don't know any other ways of getting the silver - yet.
I've seen 2 or 3 people on TH-cam do it with electrolysis and it looks pretty easy. Here's a video from Moose Scrapper: th-cam.com/video/H_LbT3mhilI/w-d-xo.html
I watched the Moose Scrapper video. That dude could really use a nice set of Corning Ware. Just sayin'.....
Great to see you back bud. I have done a lot of checking on this project. Is it really worth all the process ? I guess the end numbers say it all eh. It will be neat to see the end results my friend. Your chemistry is to be admired my friend.
Just wait until silver gets close to $100 per ounce - it's coming.
@@sreetips I have been stacking various coins, rounds for over 40 yrs. and am now pouring silver so it is a real catch 22 for me LOL.
Wish I would have found this video before I started buying silver. I have about 70 utensils that only 20 or so are not silver plated. Luckily I didn't offer much money for all of it, but I doubt I turn a profit if I refine it. Maybe it's still worth using the plated items to inquart my gold, but I'm not sure what the base metals are on some. One piece I cut up looks like a silver colored metal that turns green with silver test acid. Funny thing is every one of these pieces tested positive for silver because I didn't want to file into them before I bought them. Lesson learned! I'm not buying anymore silver unless it is stamped sterling!
Zeke, about 5% of silver jewelry marked 925 is not silver. Test each piece with schwerters. Putting schwerters on silver plated will test positive for silver. Got to go down into the metal with a file. It’s the only way, at our level, to be sure.
@@sreetips thank you. I was thinking about integrating a specific gravity test into my tests because some people obviously don't want me to file into there stuff before I buy it. Moving forward I will insist on them letting me or pass on the purchase. Honestly it seems silver plated material is everywhere and sterling is more rare than karat gold
For those I ask them if they want to know if it real. If it is then the test will reveal it and I buy the piece. If it’s not real, say silver over brass, then it’s almost worthless. If they refuse, then I walk away. A guy tried to sell me a gold bar in plastic. Before I buy I must take it out and test it. He refused so I handed it back and walked away. If they really want to sell then the test shouldn’t matter.
@@sreetips very good points. Thank you for the info.
@@sreetips I'm thinking I might use sodium sulphite in a stripping cell to get the silver plate off. It is cheap and I would rather get what silver I can off for inquarting. The silver will use less nitric acid than copper or other base metals from what I'm reading.
After all the materials and time I'd say its not worth it unless you have nothing better to do
Is there a profitavle way to process silverplate?If u include ur time its a real waste to me..Thanks for the videos I do enjoy ur process of neatness and efficientcy,your one of the best.
As long as they can print money, metal prices will remain low because they can (and do) use paper silver contracts to reduce the spot price, and therefore the demand, for physical metals. They use inflation (money printing) to kill the inflation hedge. It’s brilliant. And it works. So if your point of view is: recover the metal, sell the recovered metal to cover the cost, and end up with a “profit” then forget it. However, if you don’t have to sell the metal once you recover it, then your profit is the metal that you recover, then expense doesn’t matter.
@@sreetipsso, if I was to collect plated pieces found at garage sales and thrift stores, I could slowly add to my silver stack?
I saw a site where you could send items for retirement, wondering if that is worth it.
@@JeffJones72 I've had much better luck at estate sales than at garage sales. I've sporadically had great finds at thrift stores. Always look for the opportunity.
Regarding investing for retirement, look into opening a Roth IRA. It's funded by after-tax dollars, investments grow (ideally), and the profits can be withdrawn tax-free after 59 and half.
Canada has a tax treaty with the USA and won't tax dividends on Canadian companies held within a Roth IRA.

Silver plated is very low silver content. I’ve got a bin full of it that I’m saving. Sulfuric on silver plate is something that I’ve never done. No experience there.
@@sreetipsis it okay if I ask you for formula for volume of sulfuric acid to volume of silver??
Is my math off, or did it cost almost double the value of what was recovered? How to overcome this? Cheaper chemicals? Very insightful video, thanks for sharing your knowledge.
Your math is stop on. I was going for realizing a total yield rather than a profit. I just wanted to see how much metal was on that plated dish.
Glad to see and what is the name of your gloves what type that is
Nitrile
Glad to see ya back Kadriver ,, some of us were going through with draws 🥴
Sreetips withdrawal, cold turkey.
Ok if you use the Nitrect and distilled water 3/1 three parts water and one part acid completely covering the plated metal, no heat is NESARY with this method after about 30 minutes or when the saloution stops bubbling strain the saloution so there is no meatle, use unionized table salt adding slowly, when the salt stops dissolving and there is what looks like cottage cheese strain off all liqewed prince with clean water. The remaining is or should be 99.9 silver chloride. Total prosec should take two hours. And be safe use rubber gloves and eye protection do this outside avoid breathing any fumes are poision to the body.
I had about 1.5 liters of distilled water. 900ml nitric acid. With no heat it would take days to get everything in solution. I've got another silver plated platter. I'll do another video with no heat so we can see how long it will take to get all the copper dissolved. I'm guessing four or five days at least.
wow, that was very interesting. thank you for that. now I don't know much about everything you were doing, but I was following u. to my lay understanding. all metals of the periodic table are soluable? is that true or then my spelling.😁
Robert, nitric will dissolve silver, copper, brass, zinc. But nitric won't dissolve gold, platinum, aluminum or stainless steel. Some metals are soluble in certain acids but insoluble in others. We can use this knowledge to selectively separate metals from each other.
I would like to see you do a refining of keyboard mylars & to know if you know how you could incenerate the mylars to recover the silver
What about extracting the gold from mineralized outcrops? Like say malichite and chrysicola to get the copper out, or silver from pyrargynite? Is there a way to get the gold out of the pyrite. I have a indigo blue metal with gold veins and pyrite in it that sets my metal detector off that has copper and iron keyed out so it dont read them. I want the gold out.
Sorry, I don’t have any experience processing ore
Is it worth the effort to recover the silver plate from the back of 24" x 30" old mirror? The silver is coated with a layer of black paint. It's water damaged, so the silver peels right off glass.
I’ve never tried silver from mirrors. But my guess is very small yield.
@@sreetips Agreed... Thanks.
HI! I have a problem about silver recovery from silverplated silverware. The basic metal is zinc, then a thin layer of copper and then silverplating on. First i try to disolve whole spoon in nitric acid, but it starts to boil over the floor. I repead the proces with less concetrated nitric acid, the spoon is disolved, but i have a lot of powder on bottom, the liquid is blueish. So im guesing that zinc is on the bottom like powder, silver is in liquid? or did zinc something else to my silver? Now I will first melt the zinc away and scrap the upper layer down, and i will procced with that nugget forward
Zinc is soluble in nitric acid it will turn your solution green. Get a small sample of the blue liquid and test it with a few drops of hydrochloric acid like I did in the video. What ever is on the bottom, it shouldn't be zinc. It might be your silver.
@@sreetips Hi again. I finished disolving silverplated silverware in nitric acid, filtered it and put Hcl and nothing happened. Like no silver inside. No cloudiness... ;( Should I try put copper inside to cement silver?
But now I have second problem with recovering gold from cpu...I disolved 15cpu and few ram sticks in Hcl + hidrogen perokside (little), put those goldplating leaves in aqua regia, they disolved, filtered the liquid and today I got my smb by mail, (in Slovenia hard to buy), and surprise...nothing happened with liquid..like no mud at the bottom, still green yelowish colour...I put it so much that smb sit on the bottom...no reaction. Do you know what could go wrong? Should I put a little bit of urea inside?
Would it be more economically feasible to reverse electroplate the plated material instead of dissolving everything? Say like you had a good amount of plated silver utensils?
I don’t know how to deplete silver.
You can also melt one lead and one copper to make silver
I wasn't interested at all in this topic but I watched it all from start to finish lol
Would it be possible to rinse the plated items with acid removing the upper layer until all of the silver is dissolved and then discard or scrap the brass/copper base metal? That would reduce the amount of acid consumed.
No, the silver will cement out just as fast as it dissolves.
Very interesting video. Calculating the silver price would need to be $30.40 or higher to be worth your while but including time probably $50 or higher. That's expensive! Is there a less costly way to do it? Chemical prices are also probably higher today.
No. Getting precious metals, from any source, is never quick and easy.
@@sreetips thank you
What do you do with the copper solution, can you recover from that?
Check nurd forge . You can recover copper metal and nitric acid.
