Silver Refining Process Without Acids

[@akernelofwheat4016]

Thank you. I came here to understand how God refines His people as silver is refined. Very informative.

[@J.fromMichigan]

This is a very clear video with temperatures, equipment, and process. Good stuff.

[@michaeldenison7339]

Thanks for doing this Jason. I decided to keep my pyramid, for now, vs melting it down. What was in this . . . copper slimes from reverse electroplating silver, as well as the silver. Sweeps from a silversmithing class, including filings, snips, and balls. Also . . . a lot of solder chips that are always getting swept up. Plus some contaminated water cast silver with I believe nickle. I removed as much of the magnetic material as possible. Which was from files, broken saw blades, and steel wool.

[@uspockdad6429]

You mention slimes from electroplating silver. I always use electrorefining to purify my silver, and often times end up with a bit of PT group metals in the slimes. Have you had the pyramids tested with an XRF to see if there are any other PMs other than just silver? I’d be curious to see how pure this method actually gets silver.

[@michaeldenison7339]

@@uspockdad6429 Not electrorefining, though I do want to get a set-up to do that, I love the look of silver crystals. This is just putting silver plated items in a salt bath and hooking them up to a battery charger. It gets messy real fast. Those green clumps in the video are the copper + other base metals slimes, or salts.

[@J.fromMichigan]

Sounds good. Thanks for scrapping. I do it all the time, but am just getting into this part. I have a suggestion as to how to clean the slag off. I don’t know if you would loose content. Maybe us a 6 or 8 inch buffing wheel with rouges. Be careful with them.

[@JimNichols]

Amazing video and we are still using chemistry to remove the Ag from the mix, just not HNO3. I love the videos and while I presume I will never use this you have started me on my usual quest for knowledge. I found that Cupellation actually uses this chemical reaction to work Ag(s) + 2Pb(s) + O2(g) → 2PbO(absorbed) + Ag(l) and the first Cupel were made out of bone ashes while the best material was obtained from burned antlers of deer although fish spines could work as well. Amazing to me! Thank you very much!

[@morganandreason]

Silver dissolves less oxygen as you raise the temperature beyond the melting point, so if you want to avoid "sprouting" when it cools, just bump up the temperature at the very end before you terminate the process. Of course, cooling it down slowly also helps, as you did with the second button.

[@stephenanderle5422]

I think you are wrong. The hotter it gets the more oxygen it absorbs.

[@morganandreason]

@@stephenanderle5422 It's a well studied phenomenon. The solubility of oxygen increases with temperature in solid silver, peaks at just above the melting point, and then decreases with increasing temperature beyond that. At 973°C, the solubility of oxygen is 3050 PPM, at 1024°C it has gone down to 2950 ppm. As the temperature is increased the molecules gain in average energy and so are more able to overcome the attractive potential that keeps them in solution and thus the vapour pressure of the solvent increases and the solubility of the gas decreases. Ideally, of course, you would like to have an oxygen-free environment for a little while at the end of the process, to draw the oxygen out of the silver before it solidifies.

[@BackYardScience2000]

I always thought that the sprouts were from the silver cooling faster on the outside and shrinking while the inside was still a bit molten. Squeezing the silver out as it cools into the sprouts. I know that bismuth does this as well. Copper will shrink inward, I'm guessing because it's such a good heat conducter, and form pits while silver and bismuth form these sprouts. But I never knew that it was due to dissolved oxygen and not from the outside cooking faster than the inside. Very cool! 😎

Much of what is in what I sent him is sterling, with silver solder chips, and some copper and brass, as we work with all.

Very interesting! Thank you for creating and posting! I believe you have an xrf, if not mistaken. It might have been cool to read the silver sample at the end to see if it confirms the purity of the silver! (for those of us new to this) I haven't read up on cupelling. Does the lead go airborne, or is it all absorbed into the cup? Also, concerning your cat refining for PGMs, is the xrf any help in reading crushed honeycomb, or is the concentration to small?

[@rogerreiner1846]

Shoot off an email to the mint or large coin dealers and they will verify and validate this -- these are standards that have been known and used for over 8 decades, and the coins are collectible and worth much, much more than the silver within them.

You ended up with 26.73 grams on the first button. That is precisely the weight of a US silver dollar; which is of course 90% silver and 10% copper, but it's an interesting coincidence!

Would this work with silver / copper coins? We lost our house in a wildfire in CA in 2017. My son and I had a coin collection that partially melted.

[@chouseification]

If you already know the acid process, stick with it, as your recovery rates are astonishingly higher and your waste is much less. This process is meant to be used to understand if there's anything good in a _sample_ from a potential mine, but is not used to extract metal commerically, as it misses a lot and most importantly you need to add all that lead (and deal with cupels soaked with lead oxide afterwards, not counting however much you breathed in).

I would like to see what it cost him to do this. With the cupels, the brand new crucible, the fuel and power used. The silver itself, right now, comes to about $65. I could have just picked out the larger pieces that I knew were silver and used them in my jewelry making, which would mean a much smaller yield. But I included them to be certain that it was all silver in the end. Removing the larger pieces, that would leave the filings, the solder clips, the reverse electroplated silver. I doubt it would be worth it to refine without those other, larger silver pieces. As for copper, nah. I don't think it will ever be worth it to refine on such a small scale.

[@spiderdude2099]

Yes, if an alloy is mostly silver with 25% or less of gold, the alloy is treated with nitric acid which will leave the gold and dissolve the silver. The silver solution can then be filtered off the gold and precipitated into silver chloride with HCL or sodium chloride and reduced into pure silver metal with potassium hydroxide and sugar. The gold can be melted too. Then you end up with the silver and gold separated

[@DryLakeMiningCo49]
