I LOVE your do and don't vids!! There's alot to learn from showing the videos that you show, of what would happen when people make mistakes!! REALLY GREAT VIDEO SREETIPS!!!
Dear Sreetips I've been watching your videos for sometime and always enjoyed it . I'm a chemical engineer and I thought my advise would be helpful for you . In the case you have fine powders in the solution and you need to separate it from your liquid . The best method is to use flocculant polymer . It makes your filtration , cementation and washing process , way easier and faster .
I love the lab coats - also really appreciate you sharing your tips, they have been very helpful and really really like that you pass the safety tips along, very important. I've been doing this for a few years now and reference your videos often.
This channel is so cool, I never took Chem 101 it was just too tough for me to learn ( just never had the mentality for it) But thanks I enjoy viewing your videos!
I seem to pick up small bits from your videos that are very useful for me. The tubing you use for your vacuum tubing is what I have was curious if it would work or not. Thanks for posting you videos.
I ALWAYS learn new things from your videos. You truly are an inspiration. Thank you for taking the time and very meticulous detail that you put into each and every one of your videos. :-)
This video is awesome! Ever since I've been watching your videos, I've really wanted to see what would happen if you added to much silver/base metals. From how you have explained it in the past what would happen did happen in this experiment. I mainly wanted to see this done becoulse of the book that you have referenced in the past, telling you to add more silver/ base metals then what you do. Thank you so much for this video sreetips!
The book, Refining Precious Metal Wastes, is a little outdated. She actually encourages adding more, rather than less silver. But she also recommends mixing aqua regia 3 to 1. In one place, after you've dumped your waste solutions down the drain, to make sure and flush with plenty of water to protect the pipes.
Using two filters like you do with the cement silver processing will catch twice the AgCl and also allow extra space for the vacuum to pull through Sir. Ice cold of course. I'll make it through all your videos eventually. 👍
Sreetips. Please do a video on the EBay melted drop scrap gold bars next. Keep seeing them on your table. Maybe do like 90 grams of it and see a yield on a small amount before proceeding with the full amount. Would love to see what happens next regardless.
Yes. Adding too much silver (or copper, if that's what you're using to inquart with) will cause the gold to fall apart into a powder. Also, having a piece of non-karat gold in your batch could cause the same problem.
Is there some reason why you dont do an ammonia rinse of the gold? Also I find if my aqua regia has silver chloride in it that filtering through a normal funnel speeds up the process because of the increased surface area(if you do a fluted paper). I usually rinse the powder after sedimenting while in the beaker, add water boil, decant, add water and boil and then decant, boil with hcl, decant, boil and decant a few more times then add ammonia and decant then finally boil with water again a few times until all of the azide is gone. Decanting the ammonia directly into the used aqua regia is important as it breaks down the dangerous silver azide.
Hi sreetips. Iv been watching the inquarting videos that you have been putting out and I got to wandering. Is the amount of silver /copper vary if it is gold filled or plated rather then it just being mixed with an alloy and if it does then how is the amount differ? I have watched videos and I have yet to see what the difference is. I understand that it is used to reduce the gold to 6 karats at 25% but how it it determined if it is gold filled/plated?? Thank you for all that you do. The videos that I watch of yours are very interesting and educational. Keep up the great work.
Karat gold - inquart. Gold filled - nitric boils to recover foils. Gold plated reverse plate in sulfuric stripping cell. These three are not interchangeable. Testing the metals is the only way to tell the difference between these 3 types of scrap.
1 thing i have not seen you address as yet is, at what point do you personally stop adding SMB to the pregnant AR? Is there some visual indicator at which point you stop adding more or is it a known ratio of approx yield vs amount of SMB?
Good evening, Sir. Informative video... as always. I was hoping to pick your brain again for a moment... When refining silver using electrolysis, can you put pure silver crystal from one electrolysis run directly into the anode basket or does the pure silver crystal need to be melted into shot first. I know cement silver powder must be melted into shot first, but I wasn't sure about silver crystal.
When filtering marijuana extracts I like to get the solution as clear as possible. The technique I use to remove extremely fine cellular material is with silica gel. I use the Walmart Crystal cat litter and run it through a coffee grinder. I gently pack the stem of a funnel with cotton (or glass wool) and then the silica gel powder. The travel path is about 1" (2.5 cm) and I absolutely have to use vacuum filtration. Some filtrations take a few hours however the solution is crystal clear. The interesting thing is filtered material appears visually to only penetrate the first few millimeters of filter media. The filtration is usually single pass completely effective.
How much silver did you add (to how much gold)? I’m an assayer, we usually (try) to run 5:1. It’s frequently broken up, but never leaves any black “staining” in the solution. What point have you observed colloidal gold to form? 7:1? I’ve never gone more than 6:1
My fix for the clogged filter at 22 minutes. allow it to dry, remove it, place it in a beaker, add SMB solution, let it dry, remove and melt, by by filter mud, hello gold button
You're always so careful with your calculations. I would not have expected you to miscalculate! I haven't watched the video past 1:59 at this point but I don't see too much of a problem in dealing with the gold flakes: just use a filter paper and vacuum to remove the nitric acid solution and leave the gold in the filter paper, then continually add water to the gold residue on the filter paper with the vacuum pump still active in order to remove the nitric acid solution that is clinging to the gold flakes. I imagine that is what you're going to say next.
Copper is cheap and plentiful. So I don’t bother trying to refine copper. After it’s used to recover the silver, then it becomes waste. Not worth it to try to recover the copper. Would cost more than it’s worth.
Curious as to why you didn’t just filter and wash the silver nitrate off the gold in a vacuum funnel and avoid the problem of having to wait for gold to settle?
Hello Mrs and Mr sreetips. I enjoy seeing old clip. You fix it just fine sir🌹. Here in Norway, the winter has coming. My wife's father sit on enormest land, so we fix ore one cristhmes tree. Thanks for many.. many fine clip. Thank you both, and my god shower you in his glory. 🌹🌹🌹🌹
Hey bud what size are the glass tubes that you use for the vacuum system....ive order 3x now and still wrong...either too large or too small diameter for the rubber stoppers ....love your content
Hi sreetips, I really enjoy your videos. I'm wondering, how much silver is too much silver? I know inquartation means a quarter gold, but what if the gold is one fifth or one sixth? Also, does sample size matter? ie a few grams size as opposed to several ounces? Thank you for your time.
I think I understand. If your gold is exactly a quarter it will work, other than that you'll have trouble. Thank you very kindly for sharing your knowledge.
Hey Sreetips, I was positive in another video from the successful engineer or one of them that they said you could add a small dose of sulfuric acid to the gold like that and it will cause it to clump up for you. I'm not 100% but was fairly certain I saw that somewhere. I know this video is older but maybe one of these times give it a shot lol. Can't really hurt anything I suppose. :) Have a Great Mother's Day with your wife. :)
Streetips, what ratio of silver do you calculate for the karat gold of 10 or 14? 10K-41.5%-100%= 58.5%? what percent of that 58.5% do you think is silver? 14K same question how much of the 41.5% of base metal is silver? could this be why to much silver is being used? Thanks
The amount of silver will vary depending on who alloyed the gold, is it rose gold, or if it's white gold. Some will add more, some will add less. But it matters not when inquarting because we're not concerned with silver content of the base metals, only the gold content.
Hahaha I see you! Glad to see you doing a video on this as its happened to me before. I'm curious to know what the "buffer" amount would be when it comes to adding too much silver for inquarting.
Couldnt you just evaporate the liquid off and re-smelt the gold/silver, test the karat and restart the chemical refining? Seems much simpler to me, but maybe I am missing something...
I've tried peroxide for this Problem and silver simply decomposes it. Silver is a really good catalyst. I found that you can use electrolysis to remove the silver, I've posted a Video if you are interested.
I've watched a few of your videos now and I keep having the same question. Why not just get pair of chemical gloves instead of the unsafe material handling/ nitrile gloves you use?
@@sreetips after watching Nilered's video on the process I totally understand. I guess I just didn't know one could make so many colors with different alloys. There's even a blue gold if gold and indium or gallium are alloyed together. pretty amazing to me.
I thought you wanted to refine specifically to .999 for the refiner? What do they except for 24k? Also who then requires the .999 purity if not the refiner?
The big refiner I sell to don’t care. They’ll just throw it in with their next batch and re-refine it anyway. There’s really no reason to refine the gold. I just do it because I like it, and to make my videos. The karat gold can be held just like it is, no need to refine it. Just as long as you don’t try to melt it and ruin the markings. Then its value becomes questionable.
Dear Sreetips -Please add some diesel exhaust fluid to aquaregia solution before precipitation of gold by SMB - precitipation of gold will be clear and fast .
I learned all my refining techniques from professional refiners on the goldrefiningforum.com and not one has ever recommended putting diesel exhaust fluid in the gold prior to precipitation. What's in it?
The pros don't use urea. The best way to rid the solution of excess nitric is to add just enough nitric to just dissolve the gold. It's called incremental nitric dosing. If done correctly then there will be no excess nitric to remove. But if too much nitric is added, then the pros never use urea (diesel exhaust fluid) instead they use sulfamic acid.
I inquarted my gold to about 5k. I know 6k is desirable, but I have also seen people inquart to about 5.75ish. I am either going to go ahead with 5k, or add 2 g gold and remelt. Is 5k going to cause these extra problems? I have 8.1 g gold in 31g of silver/other. Figure another 2 grams gold will get me to about 6k 10.1/41.1
The gold can be up around 8k and it will still work.There is a "Goldie Locks" range. Too much silver and the gold crumbles to a powder making separation of the liquid from the gold difficult. Too little silver and the nitric can't penetrate into the gold properly. If done with the right amount of silver then the gold will hold together in chunks, allowing the solution to be easily poured off, and the resulting gold will be very close to three nines fine. Harold_V on the goldrefiningforum.com says that the gold content can be as high as 33% and the nitric will still be able to penetrate. Might take a little longer boiling time in the nitric. In Hoke's book, she recommends adding more silver rather than less. But my experience tells me to add less silver. Nothing worse than having the pieces of gold crumble and fall apart because I either added too much silver, or some of the karat scrap was not gold.
Yeah, I think you could have fixed this easier by adding some more karat scrap or gold in almost ANY form to your brown mud, drying it, and then melting that result and remaking the inquarted shot? After all, if you have too much silver in the mix, the way to solve that problem is to add more gold. That way, you never get silver chloride and all the attendant headaches.
@@sreetips Well, you certainly and clearly demonstrated what a complete nightmare getting silver chloride into the mix can and will be. That has great value. So the question is, assuming you realized this in time, what form of gold would you add to your gold powder for the remelt > make new shot > reinquart? Seems like it could be any form, but high karat scrap would probably be the best bet, wouldn't you say?
After removing all the silver, I'd filter the gold out, melt it into a button, weigh and recalculate and reinquart and start all over. Since the gold is very near pure then there would be no need to add more karat gold.
I actually added some non-karat gold by accident to create this problem. I counted some gold filled material as karat gold and this made the batch light on gold - by mistake. Normally I would melt and reinquart.
I'm at the 9 and a half minute mark. You have silver in the solution with the mud. Could this work, melt what you have, do a karat test then start all over to get to 27%, or a little more than 6 karat, which would be quickest continuing on or melt and restart??
@@sreetips I'm sorry for asking a question like that, I should've known that it would be answered in the vid, since you are the most thorough teacher I've ever seen or could imagine!! It was answered at the 10:47 mark!! Thank you!!!
Good morning! I think that I have made a "Rookie Mistake" hoping that you can help. I tested, with scratch stones and testing solutions, the karate gold, and added the appropriate amounts of Sterling for enquartment. I Equarted 10k 14K 18K and 22K, with Silver, all in one melt. Altogether I had 58 ounces of enquarted gold, of various karate, which I then started to boil in Nitric. The metals are almost completely into solution; however, to get them there, I had to use 70% Nitric, 35% Hcl and 100% Sulfuric to keep the metals from dropping out and cementing onto the bottom of my beaker, ( I had to sacrifice a 2,500 ml beaker to remove the metals and break them back up to get them dissolved). I've come to the conclusion, smaller amounts, of one similar karate gold, enquarted with Sterling, is optimal. Verses several karate weights of gold all together. So, gold and silver have gone into solution in Aqua Rega. All 57 ounces in two separate 2,500 ml beakers. Where do I go from here? Really wood appreciate your advice! Thank you in advance, Wade
Wade, I’m not sure what you have there. But I’m d say to anyone considering doing this to start with small amounts to get a feel before going all in, your gold is still there. Too many variables to instruct you.
@@sreetips I came to the same conclusion. I think that I'll try to capture the metals by introducing Zinc and then, well, start from scratch. It's all quite interesting, regardless. Like a murder mystery! I've "Murdered" my first run of Gold refining! Now, I get to, "Uncover" the mystery of how to get the Gold and silver out of the solution I've made! One thing that I have going for me is my curiosity and determination. I am pretty sure that you can't destroy the elements your working with. You only can lock them up in alloys or solution. I'm seeing that the trick is to be able to know how to reverse a wayward process. I'm going to keep trying until I figure this out. Your help, through your videos and advice are all very much appreciated! Wade
Wow ! Such a HUGE difference/problems just by using too much silver. Awsome demonstration. The colloidal gold - it'll just go straight through a filter paper. There's a whole lot of research about colloidal gold, especially in medical applications. It seems that thiols can be used to 'bind' to the gold nanoparticles, especially alkanethiols. Wiki mentions something about that mix having the ability to self-assemble into layers, which could offer way to separate them out. I'll try and find some actual research paper about that. Most thiols stink. Household Methane gas has no smell. They add methanethiol so it that reeks to high heaven. Turns out that Cysteine is an alkanethiol, doesn't stink and is available cheap on ebay. Might be worth doing some small scale experiments.
www.sciencedirect.com/science/article/pii/S0927775709000089 "Even a diluted (0.001 M) cysteine solution leads to a rapid assembly of gold nanoparticles" - sounds promising :)
Well, I've seen every single video of yours so you need to get busy! Just kidding, but I have seen all your videos , even your stock pot videos all the way to 15! It got so bad that I was watching videos that showed how to make your own nitric acid. Do you ever make you own? I guess to make it best you have to have a distillation set up, though I did see one guy who made "poor man's nitric acid". He had a heavy southern accent, and I'm from Texas so you know its heavy when it sounds heavy to a Texan!
That was probably AQUILLA refining, Ralph. He's from Alabama. A Texan can't hold a candle to an Alabaman when it comes to southern drawl. I'm from Iowa but been in the south for almost 35 years. Now folks back home say I have a little southern accent. But I can't hear it. Philip Bender has the best video on how to make nitric on all of youtube. A distillation apparatus is required. I get mine from GFS Chemicals but they don't sell to the public and they don't ship to home addresses. I seen a 2.5 liter bottle for $99 on eBay. Free local pick only. Highway robbery.
@@sreetips Perhaps you should get you a distillation set up. It might bring down the costs of your demonstrations that are not profitable. Nice that your sweet wife is willing to go to garage sales and thrift stores to find you all of your scrap silver and gold.
Before the 1600s silver did not tarnish. Only after sulfurous compounds from burning coal began to accumulate in the atmosphere. Tarnished silver resulted.
@@sreetips I doubt it. Volcanoes produce enough sulfur non-stop. I dont think it accumuates either. It may be worth of search-engining for a minute but it's obviously a matter of using sterling .0925 silver with copper instead of softer pure silver. Do you have any info about the alloy I'm interrested in? Is it possible to replace the copper with gold?. It's not a white gold, green gold, Electrum. Why is no one making it. I cant imagine a batter alloy for coins and jewelry. Maybe 1% platinum to make it less soft but that's it
Yes, or clean brass can be used. Copper actually works better because less likely to be any silver chloride formation. I use silver because I also refine silver.
@@sreetips Why not just going with standard ratio 10K * 0.667 14K * 1.334 18K * 2 m(ad)=[(Ki/Kf)-1]*mi m(ad): added mass Ki: intial Karat. Kf: final Karat Which is 6
My numbers are lower because I multiply the final quantity of silver by 0.95 to slightly reduce the amount of silver that I add. The gold can be as high as 30% and the nitric will still get all the silver and base metals out.
I LOVE your do and don't vids!!
There's alot to learn from showing the videos that you show, of what would happen when people make mistakes!!

Would suggest to use a centrifuge for separating the solids and a reflux condenser to get all the pm in solution
I am wondering if electrolysis can be used to some advantage in refining precious metals.
Sreetips. Please do a video on the EBay melted drop scrap gold bars next. Keep seeing them on your table. Maybe do like 90 grams of it and see a yield on a small amount before proceeding with the full amount. Would love to see what happens next regardless.

19:07 I think it's safe to say everyone knows what a filter paper does.
I like how you aren’t afraid to show some errors
Have you made a video of the refining of the waste products from the silver crystal ie what’s left in the bag?
Yes sreetips has, m.th-cam.com/video/m__zV793nC4/w-d-xo.html
Hope this helps. 😁

I try to get about 26% to 28% gold alloy
I've seen several videos where you calculated the correct amt of sterling to add during inquartation . What happened this time ?
Ya know we humans can give these chemicals names and create fancy words for the processes, but this is pure magic. And you sir are a real magician !
The difference between science and magic is being able to explain how and why to the unknown.

Once it became a powder, couldn’t you take the powder and melt it back to a solid, and start the nitric treatments from scratch?
Yes, if I was in a hurry then that would be the way to go.
Thanks for the reply. Hehe i hadn’t watched far enough into the video before I posted this, where you mentioned just that :)
Why not inquart with copper? You will not have the chloride precipitation problem with copper, and you will not need to recover the copper.
He recently put out a video where he did it with copper. It went pretty well.
The copper seemed to work better at cleaning the gold. But I refine silver too so I use silver to inquart the gold.
@@sreetipsdo you not refine the copper as well? Or is it not worth it?
Copper is cheap and plentiful. So I don’t bother trying to refine copper. After it’s used to recover the silver, then it becomes waste. Not worth it to try to recover the copper. Would cost more than it’s worth.

I’m not sure
@@sreetips went out and bought a digital caliper...5mm od at 6"....once I found the right size they became very searchable...
instead of waiting for the gold to precipitate out couldn’t you have electroplated to titanium?
What’s the percentage of all the metals being used??
Hi sreetips, I really enjoy your videos. I'm wondering, how much silver is too much silver? I know inquartation means a quarter gold, but what if the gold is one fifth or one sixth? Also, does sample size matter? ie a few grams size as opposed to several ounces? Thank you for your time.
Too much silver causes the gold to fall apart. Too little silver and the nitric won’t penetrate.
I think I understand. If your gold is exactly a quarter it will work, other than that you'll have trouble. Thank you very kindly for sharing your knowledge.
That’s incorrect. We want an alloy that’s between 27% and 37% pure gold. The “Goldie Locks” range
@@sreetips ah perfect! Thank you so much
Great job sir thanks for sharing
Interesting, as always.

Hello Pete. Have you ever did inquarting with brass? What is your opinion on it please?
Couldnt you just evaporate the liquid off and re-smelt the gold/silver, test the karat and restart the chemical refining? Seems much simpler to me, but maybe I am missing something...
Smelt; rendering metals from ore. Everything else; yes.
How much more silver did you accidentally add, percentage wise, to cause that situation?
Michael, what actually happened is; some of the gold was not karat gold, but I counted it as karat gold by mistake.
In a situation like this would adding some hydrogen peroxide help speed up the oxidation process and reduce the use of additional acids?
I've tried peroxide for this Problem and silver simply decomposes it. Silver is a really good catalyst. I found that you can use electrolysis to remove the silver, I've posted a Video if you are interested.
I’ll check it out
I've watched a few of your videos now and I keep having the same question. Why not just get pair of chemical gloves instead of the unsafe material handling/ nitrile gloves you use?
Most likely because those are lab grade and not nitril, or it happens slow enough that it's safe enough to just remove when the material is exposed
I ran some tests on different gloves in HCl, no spontaneous effects at all. Seems most inorganic matter is resistant to highly resistant of reagents
Im sure youve seen what happens with aluminum? This was cool though. Happy New Year!! 🎉
Aluminum causes problems when trying to refine gold. I don’t use it in any of my processes.
@@sreetips after watching Nilered's video on the process I totally understand. I guess I just didn't know one could make so many colors with different alloys. There's even a blue gold if gold and indium or gallium are alloyed together. pretty amazing to me.
You have very little on your eBay store. Are you discontinuing the store?
Not at all. I just don’t need to sell anything right now. Or, I don’t have anything for sale. Thank you for your interest.
Sreetips, do you know what karat gold/ percent gold the inquarted material was?
I do not know
would a centrifuge not force the powdered gold down quicker?
Yes
Does metabisulfate precipitate out silver too or just gold?
I’ve never used metabisulfate. I use sodium metabisulfite. It will precipitate the gold only.
Nice bar !
I thought you wanted to refine specifically to .999 for the refiner? What do they except for 24k? Also who then requires the .999 purity if not the refiner?
The big refiner I sell to don’t care. They’ll just throw it in with their next batch and re-refine it anyway. There’s really no reason to refine the gold. I just do it because I like it, and to make my videos. The karat gold can be held just like it is, no need to refine it. Just as long as you don’t try to melt it and ruin the markings. Then its value becomes questionable.
Dear Sreetips -Please add some diesel exhaust fluid to aquaregia solution before precipitation of gold by SMB - precitipation of gold will be clear and fast .
Diesel exhaust fluid? I wouldn't know where to find it.
@@sreetips BLUEDEF Diesel Exhaust Fluid, 2.5 gal - Walmart.com
@@sreetips - Please add diesel exhaust fluid slowly to aquaregia solution till you not see any reaction .
I learned all my refining techniques from professional refiners on the goldrefiningforum.com and not one has ever recommended putting diesel exhaust fluid in the gold prior to precipitation. What's in it?
The pros don't use urea. The best way to rid the solution of excess nitric is to add just enough nitric to just dissolve the gold. It's called incremental nitric dosing. If done correctly then there will be no excess nitric to remove. But if too much nitric is added, then the pros never use urea (diesel exhaust fluid) instead they use sulfamic acid.
Kinda wish I had the option to have taken metallurgical chemistry in school, but they didn't have anything other than basic chemistry.
You won't find much in formal education about refining precious metals. Refiners like to keep their processes secret, especially platinum refiners.
I inquarted my gold to about 5k. I know 6k is desirable, but I have also seen people inquart to about 5.75ish. I am either going to go ahead with 5k, or add 2 g gold and remelt. Is 5k going to cause these extra problems? I have 8.1 g gold in 31g of silver/other. Figure another 2 grams gold will get me to about 6k 10.1/41.1
The gold can be up around 8k and it will still work.There is a "Goldie Locks" range. Too much silver and the gold crumbles to a powder making separation of the liquid from the gold difficult. Too little silver and the nitric can't penetrate into the gold properly. If done with the right amount of silver then the gold will hold together in chunks, allowing the solution to be easily poured off, and the resulting gold will be very close to three nines fine. Harold_V on the goldrefiningforum.com says that the gold content can be as high as 33% and the nitric will still be able to penetrate. Might take a little longer boiling time in the nitric. In Hoke's book, she recommends adding more silver rather than less. But my experience tells me to add less silver. Nothing worse than having the pieces of gold crumble and fall apart because I either added too much silver, or some of the karat scrap was not gold.
Yeah, I think you could have fixed this easier by adding some more karat scrap or gold in almost ANY form to your brown mud, drying it, and then melting that result and remaking the inquarted shot? After all, if you have too much silver in the mix, the way to solve that problem is to add more gold. That way, you never get silver chloride and all the attendant headaches.
It would have been faster to melt the brown mud and chunks and start over.
@@sreetips Well, you certainly and clearly demonstrated what a complete nightmare getting silver chloride into the mix can and will be. That has great value. So the question is, assuming you realized this in time, what form of gold would you add to your gold powder for the remelt > make new shot > reinquart? Seems like it could be any form, but high karat scrap would probably be the best bet, wouldn't you say?
After removing all the silver, I'd filter the gold out, melt it into a button, weigh and recalculate and reinquart and start all over. Since the gold is very near pure then there would be no need to add more karat gold.
I actually added some non-karat gold by accident to create this problem. I counted some gold filled material as karat gold and this made the batch light on gold - by mistake. Normally I would melt and reinquart.
I'm at the 9 and a half minute mark. You have silver in the solution with the mud.
Could this work, melt what you have, do a karat test then start all over to get to 27%, or a little more than 6 karat, which would be quickest continuing on or melt and restart??
Yes, that would save much time.
@@sreetips
I'm sorry for asking a question like that, I should've known that it would be answered in the vid, since you are the most thorough teacher I've ever seen or could imagine!!
It was answered at the 10:47 mark!!
Thank you!!!
Wouldn't it have been easier to melt the gold powder and add to the next batch of karat scrap?
Yes, or just filter, melt, recalculate and reinquart and start all over. It would save much time. This took me four days because I wasn't in a hurry.
@@sreetips ah, thank you, sir for your answer and the time you spend making these videos.
Good morning! I think that I have made a "Rookie Mistake" hoping that you can help.
I tested, with scratch stones and testing solutions, the karate gold, and added the appropriate amounts of Sterling for enquartment.
I Equarted 10k 14K 18K and 22K, with Silver, all in one melt. Altogether I had 58 ounces of enquarted gold, of various karate, which I then started to boil in Nitric.
The metals are almost completely into solution; however, to get them there, I had to use 70% Nitric, 35% Hcl and 100% Sulfuric to keep the metals from dropping out and cementing onto the bottom of my beaker, ( I had to sacrifice a 2,500 ml beaker to remove the metals and break them back up to get them dissolved).
I've come to the conclusion, smaller amounts, of one similar karate gold, enquarted with Sterling, is optimal. Verses several karate weights of gold all together.
So, gold and silver have gone into solution in Aqua Rega. All 57 ounces in two separate 2,500 ml beakers. Where do I go from here? Really wood appreciate your advice!
Thank you in advance,
Wade
Wade, I’m not sure what you have there. But I’m d say to anyone considering doing this to start with small amounts to get a feel before going all in, your gold is still there. Too many variables to instruct you.
@@sreetips I came to the same conclusion. I think that I'll try to capture the metals by introducing Zinc and then, well, start from scratch.
It's all quite interesting, regardless. Like a murder mystery! I've "Murdered" my first run of Gold refining! Now, I get to, "Uncover" the mystery of how to get the Gold and silver out of the solution I've made!
One thing that I have going for me is my curiosity and determination. I am pretty sure that you can't destroy the elements your working with. You only can lock them up in alloys or solution. I'm seeing that the trick is to be able to know how to reverse a wayward process.
I'm going to keep trying until I figure this out. Your help, through your videos and advice are all very much appreciated!
Wade
Always informational excellent
Cody never shakes the camera
What size beaker are you using for this reaction?
Probably two liter tall form beaker. They are my work horses.
Hello. What would you say will work the best to neutralize acid? Salfamic acid or urea ?
I have professional refiners telling me that urea don't work. Sulfamic is the way to go. They know way more than I do so I follow what they say.
sreetips Thank you. I sincerely appreciate it.
Would you say : ferrous sulphate or SMB ?
another great video
Saved it...nice!!!
Vv congratulations sir
Wow ! Such a HUGE difference/problems just by using too much silver. Awsome demonstration.
The colloidal gold - it'll just go straight through a filter paper.
There's a whole lot of research about colloidal gold, especially in medical applications.
It seems that thiols can be used to 'bind' to the gold nanoparticles, especially alkanethiols.
Wiki mentions something about that mix having the ability to self-assemble into layers, which could offer way to separate them out. I'll try and find some actual research paper about that.
Most thiols stink. Household Methane gas has no smell. They add methanethiol so it that reeks to high heaven.
Turns out that Cysteine is an alkanethiol, doesn't stink and is available cheap on ebay.
Might be worth doing some small scale experiments.
I actually added some gold filled material to the batch by mistake, I think. This had the same net effect of adding too much silver.
www.sciencedirect.com/science/article/pii/S0927775709000089
"Even a diluted (0.001 M) cysteine solution leads to a rapid assembly of gold nanoparticles" - sounds promising :)
Good job..
Wonderful information! Thank you
All sulfide metals have gold
He looks like Ronald Regan's cousin.
lol almost speaks and sounds like him as well LOL That was a good one ;)
what if instead of adding siver you put in pure gold
That depends, at what point in the process you are referring.
could have been worse you might have invented the way of the alchemist to turn gold into lead!!
the hair is always good
This is awesome 😮
Well, I've seen every single video of yours so you need to get busy! Just kidding, but I have seen all your videos , even your stock pot videos all the way to 15! It got so bad that I was watching videos that showed how to make your own nitric acid. Do you ever make you own? I guess to make it best you have to have a distillation set up, though I did see one guy who made "poor man's nitric acid". He had a heavy southern accent, and I'm from Texas so you know its heavy when it sounds heavy to a Texan!
That was probably AQUILLA refining, Ralph. He's from Alabama. A Texan can't hold a candle to an Alabaman when it comes to southern drawl. I'm from Iowa but been in the south for almost 35 years. Now folks back home say I have a little southern accent. But I can't hear it. Philip Bender has the best video on how to make nitric on all of youtube. A distillation apparatus is required. I get mine from GFS Chemicals but they don't sell to the public and they don't ship to home addresses. I seen a 2.5 liter bottle for $99 on eBay. Free local pick only. Highway robbery.
@@sreetips "Poor Mans nitric acid" didn't reveal his name
@@sreetips Perhaps you should get you a distillation set up. It might bring down the costs of your demonstrations that are not profitable. Nice that your sweet wife is willing to go to garage sales and thrift stores to find you all of your scrap silver and gold.
East asian sreetips: This bar is just like my son, a failure.
too much silver i no a time when i had too much silver
Can you make 99% silver 1% gold?
Would it not tarnish?
I don't think so. Sterling tarnishes because of the copper alloyed with the silver. Pure silver does not tarnish, very much.
Before the 1600s silver did not tarnish. Only after sulfurous compounds from burning coal began to accumulate in the atmosphere. Tarnished silver resulted.
@@sreetips I doubt it. Volcanoes produce enough sulfur non-stop. I dont think it accumuates either. It may be worth of search-engining for a minute but it's obviously a matter of using sterling .0925 silver with copper instead of softer pure silver. Do you have any info about the alloy I'm interrested in? Is it possible to replace the copper with gold?. It's not a white gold, green gold, Electrum. Why is no one making it. I cant imagine a batter alloy for coins and jewelry. Maybe 1% platinum to make it less soft but that's it
Hi, why do you inquart with silver not copper?
Because I refine silver also. By using silver to inquart I’m essentially refining both metals simultaneously. Like killing two birds with one stone.
are those bars beside your scales them fake bars from israel
How do i know how much silver do i need to Add to my 14 k gold?
Weight of the 14k times 1.265 equals amount of sterling/925 silver needed to inquart the 14k
I wish I knew what you were doing
He is refining gold..
did I understand that you can inquart with copper instead of silver/
Yes, or clean brass can be used. Copper actually works better because less likely to be any silver chloride formation. I use silver because I also refine silver.
Very very nice sar
Inquarting
Hi SCREETIPS your an art american i love you
How do you work out how much silver to add.
10k multiply grams times 0.635
14k multiply grams times 1.265
18k multiply grams times 1.9
@@sreetips Why not just going with standard ratio
10K * 0.667
14K * 1.334
18K * 2
m(ad)=[(Ki/Kf)-1]*mi
m(ad): added mass
Ki: intial Karat. Kf: final Karat Which is 6
My numbers are lower because I multiply the final quantity of silver by 0.95 to slightly reduce the amount of silver that I add. The gold can be as high as 30% and the nitric will still get all the silver and base metals out.
