Why melt silver together with gold then remove the silver? Does a silver-gold blend create some form of reaction in the gold that is left after removing the silver?
I'd like to know too. I suspect that this makes it easier to get the proportions of acid right so that you end up with silver and gold in solution and minimize toxic chlorine gas during the process. But then, why not add enough silver to the 14K gold to make it 10K gold and then go with a uniform 10K gold alloy ?
The nitric acid will not penetrate 14k gold. I add silver to reduce the karat down around 6k or 7k. With the gold content this low, then, and only then, will the nitric be effective and get all the silver and base metals out.
ah, so the idea is to create the low gold-percent alloy such that by extracting the silver we end up with a sponge-like gold substrate that can be dissolved faster in aqua regia ?
Max, that's a beautiful, concise, and compact way to get that point across. I couldn't have said it any better myself. I may use your words in a future video about inquarting. Thank you!
Make sure you use 30 percent peroxide. The reaction will give you water vapor and no brown nitrous fumes because you have solubilized the nitrous oxides as prompt oxides of nitrogen with the peroxide now you have close to 98 percent efficiency. Less corrosion of your hood and better reaction kinetics

Since nitric acid isn't cheap, that brown nitrogen dioxide gas we see is money going right out the fume hood exhaust. I'm not sure if it's cost effective or not, but you can bubble the nitrogen dioxide gas through concentrated hydrogen peroxide to reform nitric acid. The acid will be relatively pure, but you will likely have to distill the acid to bring it back up to azeotropic strength. Concentrated peroxide isn't cheap, but it may be worth a cost analysis. As you probably know, that exhaust NO2 just ends up acidifying outdoor precipitation.
45:10 You got more Platina in the solution I believe? That means that nitric acid and muriatic acid is dissolving the available browned gold, but the mixture of browned cakes just opened itself that leads to more amount of different metal? Since it would be better to ground the brown cakes first with a machine grinder? Or is the process of the brown cakes already dissolved? But perhaps the grey colour in the beaker is probably something that weighs more than Gold? Its molecular weight describes either concentration of gold or perhaps other metals all ranging from palladium to silver, but silver should have been dissolved with both acids. But then again are we looking at perhaps Platina as its weight is so heavy that it doubles its presence to lay at the bottom? As Platina is 195 weighable as molecule AU?
@@sreetips Sorry, I wish I've had all the laboratory like you so I could at least show this, wait 2 more years and I'll show you the things that I go around and think. In my belief, there is this that molecular weight often makes Platina residue as blackish coloured substances that sometimes end up in your filters and are the last residue in the solution. Because of the high molecular weight of 195 Platina is as well hard to split up from the particles it is mixed together with. But it also would be behind in the beaker. Some would think that the steel would be residue, but on the other hand, steel is an alloy by reducing the carbon like in Iron. Correct me if I'm wrong. If acid does not bite steel then it's different measure about that. So we are most likely are talking about steel and Platina together being residue in the beaker. Splitting steel from Platina I believe you will need to use the lead method like perhaps cleaning gold bars. By molecular weight, you might end up having Acid on the bottom of the solution that is mixed with water over a long period of wait. By this, you don't see it but you can know what you see that the acid is on the bottom of the beaker after some time. Here we do not speak about Acid that has been used or is with a different solution than just water. Since water has low molecular weight than Acid. And what is with most molecular weight does end up on the bottom of the water solution. Water perhaps has weight 18, 2 of Hydrogen and 16 of Oxygen. And the molecular weight of Acid is also important to know. I believe that measuring the molecule weight has a big issue in your chemical procedures, as it states what often is on the bottom of a beaker after processing. I've been super studying all your videos over time and liked all of them, so I've also been studying these things I wrote about. It is just that I know the logic of this, not fully being educated at a school. This chemical processing gave me my life back to reality means that my life has some sort of meaning. It was hard for so long not having a purpose to live. Thanks for all your videos! They are a great motivation for a better day. Soon I will be ahead and having similar laboratory. Not amateur laboratory-like out in the woods cooking with acid and dying younger by the fumes that come out. People seldom do see your face making the videos, and seeing you using a professional mask and eyeglasses.
The cost comes from scarcity. Refining is generally difficult, no matter what substances. Yet, they have managed to optimize and automate the processes so that the refined substances cost nearly nothing. Not so with gold. It's just a scarce element.
I started stocking up on some karat scrap to do a refining and add to the yield on the gold filled scrap im planning to recover gold from. Among the karat scrap are some enameled pieces like lapel pins. Will the enamel just burn off in the inquartation or does it need special treatment? Thx, as always......great video.
I try to remove most of that by using two pairs of wire cutters. Hold the enameled piece with the cutters and bending back and forth until most of the enamel chips and breaks away. I don’t think it hurts the batch, but I remove all that I can.
he's afraid of someone stealing his shit quality gold, lmaoo 11 grand? more like 11 cents this shit is 9 carat at best, probably mixed with cheap alloy too
Please do yourself a favor and watch this at 2x speed. You can still understand everything, but you don't feel like you need to take an intermission break.
Watching in 1.5x is funny because it seems he rushes everything. The mistakes are highlighted like when a ring drops out of the melt dish in the beginning. Also it makes it seem like he's extra excited about the math. Lol
It looks like you are using a vacuum pump to transfer the acid into a glass container. Any recommendations on a vacuum pump, if that is what you are using?
Yes, I use an HVAC vacuum pump from harbor freight about $100 it's been in use for almost 9 years. I made a video on my vacuum system, it's posted on my channel.
when you primary smelt gold from ore it comes out as electrum which is the base of white gold. Lots of that unrefined white gold was used to make jewelry over a hundred years ago. They just didnt go any further because it wasnt worth it. And they were right its not worth it because he probably spent several thousand dollars in acid, sodium Meta Bi sulfate and other chemicals and glassware to come out with the bar of gold.
Adding the silver, then removing it with nitric acid, does an amazing job of cleaning the gold in preparation for refining the gold with aqua regia. Trying to dissolve the gold "as is" has two major flaws: first, karat gold contains silver. The hydrochloric acid in the aqua regia will react with the silver in the karat gold forming silver chloride and make filtering a nightmare. Second, if the silver content in the karat gold is high then the HCl in the aqua regia would cause passivation. Passivation is a thick crust of silver chloride that forms on the karat gold and shields the gold from the acids. Once this layer forms it must be removed before the gold will dissolve. Adding silver and parting with nitric acid, if done correctly, completely eliminates both of these problems. If I tried to dissolve the gold without inquarting with silver then I'd still be out there trying to get the gold cleaned up, right now!
Ok I get the nitric acid to dissolve the unwanted metals. I get that the karat gold has silver in it. But why add the extra silver. That's where i'm confused. Why not just add nitric to the karat gold in order to dissolve the unwanted metals before the aqua?
@@sharudd So I've done some research on this since asking this question yesterday. It seems that if you want to remove 100% of the gold from the karat gold (or as close as possible), you have to add silver so the gold atoms are further displaced by the excess mixed in silver. This makes it that the silver has less of a chance to inhibit the dissolving of the gold atoms by means of creating a protective layer/capsule around the gold atoms, thus ensuring the maximum amount of gold gets dissolved by the acids. As recommended by @Biomorphs in the comments, Cody'sLab has a great video on this (just look up "Cody'sLab Inquarting"). Hope this helps.
Angelo, thrift stores, consignment shops, resale stores, goodwill, but mostly yard sales. Take a look at my video titled " how to make a profit refining precious metals"
@Firebuster Massively appreciate that, but surely one (or maybe even two) named object(s) per shot is enough? sometimes you've got like 5 tags visible and it just looks a little silly >.< please keep up the good informative content though! :)
Pieces of glass added to a boiling solution to prevent the solution from "bumping". Bumping happens when steam bubbles build up heat and release it explosively. Sometime with enough force to break the beaker. The boiling granule wil draw the heat and prevent the boiling solution from bumping.
Where did the filters go? Pardon my ignorance but would that not have added impurities when it was dissolved down or turned into a bar with the filter paper and the gold? Did you remove slag from the liquid gold?
1:04:00 You should have collected the filter and remove the cake out of it. Though there is still some residue of Platina? It's weighting most so after the start of pouring the solution you got a black filter, but then when you moved the cake out it still got few Platina residue. I believe your bar was 0.998 clean?
The nitric acid will more easily dissolve the non-gold if you inquart it a bit stronger, not to 27% gold but as low as 20%. It also helps if you make sure it is well mixed and dispersed into the smallest pieces possible.
I have a question about saving time. once the metal has been inquarted. instead of melting into the drops in the water, couldnt you melt into small bars,the run through a rolling mill until its very thin? Then, use the nitric acid so you dont have such thick globs of metal to work with?
If the alloy was rolled out and then cut into sheets or strips, they will stack on each other like decks of cards at the bottom of the reaction vessel and less surface area would be exposed to the acid. You would then need to separate them and by doing so crush the gold sponge into a powder. Seems like more work and possibility for loss.
C. M. Hoke Refining Precious Metal Wastes page 39. PRELIMINARY TREATMENTS You first want to get your material in such form that it will be easy for the nitric acid to reach the base metals and dissolve them. The treatment will differ for different kinds of material. Old gold jewelry, clippings, and old dentures should be hammered flat and rolled thin, the thinner the better. Every minute at the rolls saves many minutes at the acids. Feed the pieces into the rolls with a little scoop whose sides have been cut out so that they will fit against the rolls closely; or put them on a piece of paper, and feed in paper and all. Cut the rolled pieces up into short lengths, twisting them so they will not lie flat in the acid; then anneal. And further on the following pages. Without Inquarttion! And many thanks for the uploads, much appreciated Best regards, Richard.NL@@sreetips

@@antigen4 well, what he was trying to do was make both types of gold into the same karat.... its implies the 14k needs more silver to bring it down to the same level as the 10k
The way I'm understanding is that he need's a quantity of silver to gold. 10k has less gold therefore needs less silver, 14k has more gold and needs more silver.
Great video and explanation as to why you add the silver initially. Have you refined gold nuggets which include quartz and other crystallised minerals? My grandad used to amalgamate with copper and mercury then heat it off in retort. Is there a better / safer lab method? Tia
I don't have any experience with minerals mixed with gold. All the gold I deal with come from scrap jewelry. I've never used mercury in any of my processes. But the karat gold can be inquarted with just clean copper or brass. No need to use silver. I use silver because I refine silver also.
Anthony, yes! The beauty of using silver is this; the silver would have been dissolved as a first step in refining the silver. Using it to inquart the gold is like killing two birds with one stone.
@@sreetips Very cool, I figured as much. Would you consider doing a video on the silver extraction. I seen your video on replacing the Anode, but maybe a more descriptive video on the process and setup of the extraction?
If we had a monetary system where gold & silver are embroiled into the paper of dollar$, you could then use this process to reclaim the gold back out of the money.
Why did you use silver when initially melting your gold pieces? Was it to make the process of heating the reaction quicker? Is silver a necessity towards the valuable gain?
Wow. Very awesome. Did you have to melt it with the silver, first? Could the same process remove the other metals directly from the 10K and 14K gold without the silver?
Yes, adding silver has to be done first. Then remove the silver and base metals with nitric. Then refine the gold with aqua regia. I've tried going straight to aqua regia and end up with a mess.
@@sreetips Thanks for answering. Have you tried nitric just on the 10K and 14K gold? Doesn't Nitric remove all of the base metals? I don't get why the need for silver.
Copper is used to cement out the silver and any traces of platinum group metals. Then everything is rinsed, melted into granules and parted in the silver cell. The waste copper solution is cemented on iron. The copper metal is thrown away and the iron solution is treated with sodium hydroxide.
@@sreetips thank you very much for the help and videos. I dont want to mess with the PGMs. I just wanted to waste as little of the other metals as possible. Pulling out the gold and silver are good enough. You've made it very clear that platinosis is very dangerous and I dont want to mess with it.
Cool video thank you SREETIPS! Is it easier to do it your way that you showed us or would it be easier just to dissolve everything at one time and then drop everything out separately? One other question, How do you obtain all your jewelry? Thank you in advance.
Inquartation is the easier softer way. If I tried "just to dissolve everything at one time" then I would still be there trying to get the gold purified. Inquartation eliminates MANY problems.
Do you know that the Nitric/Water combo has run it's course when the fumes cease? Or are you just going by the time you have it sitting in the solution?
Seems to me like running the gold BB's though a set of rollers to flatten them out would really cut down the amount of time it takes for the process to work, and the amount of solution required to dissolve all the non gold product.
Its crazy how many steps you had to go through to do this. I have respect for you to learn such a skill. Great video thanks for sharing

And what is with most molecular weight does end up on the bottom of the water solution. Water perhaps has weight 18, 2 of Hydrogen and 16 of Oxygen. And the molecular weight of Acid is also important to know.
I believe that measuring the molecule weight has a big issue in your chemical procedures, as it states what often is on the bottom of a beaker after processing.
I've been super studying all your videos over time and liked all of them, so I've also been studying these things I wrote about. It is just that I know the logic of this, not fully being educated at a school. This chemical processing gave me my life back to reality means that my life has some sort of meaning. It was hard for so long not having a purpose to live. Thanks for all your videos! They are a great motivation for a better day. Soon I will be ahead and having similar laboratory. Not amateur laboratory-like out in the woods cooking with acid and dying younger by the fumes that come out. People seldom do see your face making the videos, and seeing you using a professional mask and eyeglasses.
No wonder it costs so much for certain types of luxury metals
The cost comes from scarcity. Refining is generally difficult, no matter what substances. Yet, they have managed to optimize and automate the processes so that the refined substances cost nearly nothing. Not so with gold. It's just a scarce element.
I started stocking up on some karat scrap to do a refining and add to the yield on the gold filled scrap im planning to recover gold from. Among the karat scrap are some enameled pieces like lapel pins. Will the enamel just burn off in the inquartation or does it need special treatment? Thx, as always......great video.
I try to remove most of that by using two pairs of wire cutters. Hold the enameled piece with the cutters and bending back and forth until most of the enamel chips and breaks away. I don’t think it hurts the batch, but I remove all that I can.
@@sreetips thats a great idea. Thx again

he's afraid of someone stealing his shit quality gold, lmaoo 11 grand? more like 11 cents this shit is 9 carat at best, probably mixed with cheap alloy too
Hi do I have to add silver mandatory ?or it can be done with copper thanks great video
Copper works even better, less silver chloride to deal with. But copper takes about 1/3 more nitric to dissolve completely.
Please do yourself a favor and watch this at 2x speed. You can still understand everything, but you don't feel like you need to take an intermission break.
I watch EVERYTHING at 2× speed. People speak SO slow. A 5 minute video doubles in length from speaking so slowly
Especially when your wanting some quick information but the narrator drags on and on about stuff that’s totally irrelevant to the info I seek.
@@sreetips i Watch you normal, Think its a good video, just my tempo. Thank you for your work and for enlightened me..
Respect.
Watching in 1.5x is funny because it seems he rushes everything. The mistakes are highlighted like when a ring drops out of the melt dish in the beginning. Also it makes it seem like he's extra excited about the math. Lol
It looks like you are using a vacuum pump to transfer the acid into a glass container. Any recommendations on a vacuum pump, if that is what you are using?
Yes, I use an HVAC vacuum pump from harbor freight about $100 it's been in use for almost 9 years. I made a video on my vacuum system, it's posted on my channel.
Thank you. I'm surprised but very appreciative of how fast you respond to questions.
OK, great, I found your video on the vacuum system. Enjoyed watching it, very good.
Imagine leaving your 10+k$ worth of gold in that acid, and find out that it dissolved everything and chemistry is a lie
lmao
Mr. Sreetips. Is there any way you could do a video of refining silver contacts specifically to see how to get any tungsten separated from the silver?
Tungsten and silver in solution. I've never worked with those two.
I don't understand. If you are dissolving the silver out in the end then why add it in the first place? Can someone explain?
Inquarting - if you search it on you tube - Cody'sLab
has a great video to explain it all
when you primary smelt gold from ore it comes out as electrum which is the base of white gold. Lots of that unrefined white gold was used to make jewelry over a hundred years ago. They just didnt go any further because it wasnt worth it. And they were right its not worth it because he probably spent several thousand dollars in acid, sodium Meta Bi sulfate and other chemicals and glassware to come out with the bar of gold.
Adding the silver, then removing it with nitric acid, does an amazing job of cleaning the gold in preparation for refining the gold with aqua regia. Trying to dissolve the gold "as is" has two major flaws: first, karat gold contains silver. The hydrochloric acid in the aqua regia will react with the silver in the karat gold forming silver chloride and make filtering a nightmare. Second, if the silver content in the karat gold is high then the HCl in the aqua regia would cause passivation. Passivation is a thick crust of silver chloride that forms on the karat gold and shields the gold from the acids. Once this layer forms it must be removed before the gold will dissolve. Adding silver and parting with nitric acid, if done correctly, completely eliminates both of these problems. If I tried to dissolve the gold without inquarting with silver then I'd still be out there trying to get the gold cleaned up, right now!
Ok I get the nitric acid to dissolve the unwanted metals. I get that the karat gold has silver in it. But why add the extra silver. That's where i'm confused. Why not just add nitric to the karat gold in order to dissolve the unwanted metals before the aqua?
@@sharudd So I've done some research on this since asking this question yesterday. It seems that if you want to remove 100% of the gold from the karat gold (or as close as possible), you have to add silver so the gold atoms are further displaced by the excess mixed in silver. This makes it that the silver has less of a chance to inhibit the dissolving of the gold atoms by means of creating a protective layer/capsule around the gold atoms, thus ensuring the maximum amount of gold gets dissolved by the acids. As recommended by @Biomorphs in the comments, Cody'sLab has a great video on this (just look up "Cody'sLab Inquarting"). Hope this helps.
Can you make video about separation of silver ,nickel ,palladium and cu. from nitric acid that dissolve in it
Lovely video, next I have to see if you have a video of working the silver.
Hello! A very informative video, where do you get your scrap gold?
Angelo, thrift stores, consignment shops, resale stores, goodwill, but mostly yard sales. Take a look at my video titled " how to make a profit refining precious metals"
Thanks!
good video, but I think you should put your name on more objects in the video :'D
😹😹😹
@Firebuster Massively appreciate that, but surely one (or maybe even two) named object(s) per shot is enough?
sometimes you've got like 5 tags visible and it just looks a little silly >.<
please keep up the good informative content though! :)
What are boiling granules?
Pieces of glass added to a boiling solution to prevent the solution from "bumping". Bumping happens when steam bubbles build up heat and release it explosively. Sometime with enough force to break the beaker. The boiling granule wil draw the heat and prevent the boiling solution from bumping.
@@sreetips that is something I've never heard of! I love learning something new, thanks for the info and your great vids.
bet this dude has a whole room dedicated to distilled water.
Where did the filters go? Pardon my ignorance but would that not have added impurities when it was dissolved down or turned into a bar with the filter paper and the gold? Did you remove slag from the liquid gold?
1 gm of pure gold = 40.94 USD then 274*40.94=11234$
Good luck
1 Gram = 1g ( not gm that's a automobile company)
@@LocoMe4u I must say : Thanks.
@@AbuOmar1974 Nom problem

Could you show how you get silver from solutions obtained during the purification of gold?
that 279.63 also contains the 2 steel pieces
Very Labour and time intensive not forgetting the materials you have to acquire to do this process 👏 bravo mate!
This is a perfect video nice job Sreetips ;)
Hey bro good to see you here!
1:04:00 You should have collected the filter and remove the cake out of it. Though there is still some residue of Platina? It's weighting most so after the start of pouring the solution you got a black filter, but then when you moved the cake out it still got few Platina residue. I believe your bar was 0.998 clean?
PURE GOOOOLD!!!!!
Is it just me or can you hear him saying gold with extra "O's" too!
GUUULD
He sounds just like Yosemite Sam when he says that
The nitric acid will more easily dissolve the non-gold if you inquart it a bit stronger, not to 27% gold but as low as 20%. It also helps if you make sure it is well mixed and dispersed into the smallest pieces possible.
i always though it was "streetips" .. wow, 1h of bamboozled
Sreetips stays strapped with the gold nearby. Love it
I feel like you need to LOGO way more you don't have enough already
STREETIPS
I have a question about saving time. once the metal has been inquarted. instead of melting into the drops in the water, couldnt you melt into small bars,the run through a rolling mill until its very thin? Then, use the nitric acid so you dont have such thick globs of metal to work with?
possibly, but I've never tried it nor have I heard of any of the pros doing this.
If the alloy was rolled out and then cut into sheets or strips, they will stack on each other like decks of cards at the bottom of the reaction vessel and less surface area would be exposed to the acid.
You would then need to separate them and by doing so crush the gold sponge into a powder. Seems like more work and possibility for loss.
C. M. Hoke Refining Precious Metal Wastes page 39.
PRELIMINARY TREATMENTS
You first want to get your material in such form that it will be
easy for the nitric acid to reach the base metals and dissolve them.
The treatment will differ for different kinds of material.
Old gold jewelry, clippings, and old dentures should be hammered
flat and rolled thin, the thinner the better. Every minute at
the rolls saves many minutes at the acids. Feed the pieces into the
rolls with a little scoop whose sides have been cut out so that they
will fit against the rolls closely; or put them on a piece of paper,
and feed in paper and all.
Cut the rolled pieces up into short lengths, twisting them so they
will not lie flat in the acid; then anneal.
And further on the following pages.
Without Inquarttion!

How much did you pay for the scrap, glassware, and chemicals all together?
Scrap cost between 5 to 7 thousand dollars. Chemicals, glassware, electric, rent, taxes, insurance all in about $100.
When you can’t spell ‘experiment’ you know it’s going to be good.
Or round his decimals
Let's see how much gold and silver you've refined out of various objects.

Man you really put a ton of effort in this. I really appreciate it!
voice and face do not match. the voice is looks gangster and the face is a highbrow doctor.
How about a mad scientiest or an evil professor?
After all that refining, do you just throw in ice cubes from the fridge?? No impurities get added?
Not enough to report in the assay.
You seems a little confused by the math so hope this helps
Multiplying by 1.265 is just increasing your starting weight by 26.5%
Multiplying by 0.635 finds 63.5% of your starting weight
the only one confused here is you... like what "starting weight" are you even talking about? i dont think you understood his calculations at all
he's right- the multiiplier makes ZERO sense - it assumes that 14karat gold is more 'pure' than 24k gold
@@antigen4 well, what he was trying to do was make both types of gold into the same karat.... its implies the 14k needs more silver to bring it down to the same level as the 10k
The way I'm understanding is that he need's a quantity of silver to gold. 10k has less gold therefore needs less silver, 14k has more gold and needs more silver.
Great video and explanation as to why you add the silver initially. Have you refined gold nuggets which include quartz and other crystallised minerals? My grandad used to amalgamate with copper and mercury then heat it off in retort. Is there a better / safer lab method? Tia
I don't have any experience with minerals mixed with gold. All the gold I deal with come from scrap jewelry. I've never used mercury in any of my processes. But the karat gold can be inquarted with just clean copper or brass. No need to use silver. I use silver because I refine silver also.
Wow..you should write bed time stories 😴
Will the nitric acid dissolve brass? Awesome thank you for the info and quick reply.
Brass is an alloy of copper and zinc, both soluble in nitric acid. The answer is yes.
why this is on my recommendation, and why I am still watching it after one hour
I just watched this great video. It's awesome, but I was wondering if you could explain why do you need to add silver to your gold alloys? Thanks
To dilute the gold so nitric can penetrate
Great video. Where do you source your jewelry from? And where do you buy the acids?
We buy scrap gold at yard sales and estate sales. I buy most acids from Ace Hardware. Nitric from dudadiesel.com
Are those brown fumes poison? How you protect yourself from inhaling them?
Yes, I use a fume hood
This is awesome method, do you refine the silver out of your waste green nitric solution?
Anthony, yes! The beauty of using silver is this; the silver would have been dissolved as a first step in refining the silver. Using it to inquart the gold is like killing two birds with one stone.
@@sreetips Very cool, I figured as much. Would you consider doing a video on the silver extraction. I seen your video on replacing the Anode, but maybe a more descriptive video on the process and setup of the extraction?
Check my other videos. I've done several on refining silver.
Hello. Thanks for making these videos and teaching this.
How much did the scrap gold cost?
We probably paid in the neighborhood of 5 to 7 thousand.
Not sure. I record each purchase for tax purposes but I don't track the cost for each batch.
If we had a monetary system where gold & silver are embroiled into the paper of dollar$, you could then use this process to reclaim the gold back out of the money.
Why did you use silver when initially melting your gold pieces? Was it to make the process of heating the reaction quicker? Is silver a necessity towards the valuable gain?
Yes! Adding silver reduces gold concentration so that the nitric can penetrate. No silver, no reaction.
Thank you for your quick response. Do the silver have to be pure silver?
Wow. Very awesome. Did you have to melt it with the silver, first? Could the same process remove the other metals directly from the 10K and 14K gold without the silver?
Yes, adding silver has to be done first. Then remove the silver and base metals with nitric. Then refine the gold with aqua regia. I've tried going straight to aqua regia and end up with a mess.
@@sreetips Thanks for answering. Have you tried nitric just on the 10K and 14K gold? Doesn't Nitric remove all of the base metals? I don't get why the need for silver.
What do you use to precipitate the other soluble metals back out in order to not waste things like copper and silver? Thank you for the videos
Copper is used to cement out the silver and any traces of platinum group metals. Then everything is rinsed, melted into granules and parted in the silver cell. The waste copper solution is cemented on iron. The copper metal is thrown away and the iron solution is treated with sodium hydroxide.
@@sreetips thank you very much for the help and videos. I dont want to mess with the PGMs. I just wanted to waste as little of the other metals as possible. Pulling out the gold and silver are good enough. You've made it very clear that platinosis is very dangerous and I dont want to mess with it.
Now, How do you get the Silver out of the Nitric Acid Solution?
I made a video that shows how it's done.
Cool video thank you SREETIPS! Is it easier to do it your way that you showed us or would it be easier just to dissolve everything at one time and then drop everything out separately? One other question, How do you obtain all your jewelry? Thank you in advance.
Inquartation is the easier softer way. If I tried "just to dissolve everything at one time" then I would still be there trying to get the gold purified. Inquartation eliminates MANY problems.
@@sreetips ok I see, thank you!
What do you do with the Nitric Acid to get the Silver and other metals out? or do you care to refine those out?
I recover all the silver
Do you know that the Nitric/Water combo has run it's course when the fumes cease? Or are you just going by the time you have it sitting in the solution?
Also how many times do you usually run it through solution? Is there a standard method you use as far as how many times you purify it?
I can tell when you do the 5th treatment that the red smoke seems to be almost non existent
Also, when you're adding Sodium Metabisulfite, the color of the foam indicates wether or not there is more Gold to be precipitated?
Where do you typically get ahold of the karat scrap for your refining?
Local sales
Seems to me like running the gold BB's though a set of rollers to flatten them out would really cut down the amount of time it takes for the process to work, and the amount of solution required to dissolve all the non gold product.
Possibly, if time was critical. But it would add another step in the process.
