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.

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.

@@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.

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

I’m just now getting into collecting silver and gold , but this right here is the coolest thing I’ve ever seen !!! I’m gonna try it one of these days

I gotta say that, that was really cool. I've seen several vids on this before but the silver sprouts was something I've never seen! Have a GREAT Day!!!

Nice one. Ho to refine gold from ore with out using acid, can you make a video about that? Thanks

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!

Hi Jason Thank You for you time and share, Gonzalo From Baja Mexico

Great video and amazing how good your hands look!

I like those silver sprouts. I've refined silver and poured small bars but have never seen any sprouts. But when my silver is pure I do see concentric cooling lines that show up on the exposed smooth, shiny surface of the bar as it cools after pouring. I use a torch and borax for melting. Thanks for the many informative videos.

I have an affinity for melted metal. Good job.

Really cool your videos are very informative and fun to watch.

nice thank you for sharing the adventure and information on this smelting

7:34 that should be the thumbnail, looks so mesmerizing.

Great channel, keep em coming Jason

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! 😎

Thanks, enjoyed the process! amazing.

These are great videos, very informative.

Well done! Love this stuff!!

I'm not in the metal refining business but this is a lot of fun to watch

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

Жыл бұрын

@@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.

I liked the sprouts. Good info to have though. One day I'll melt my black sands. Great vid!

Love your channel please keep them videos coming. Where u buy your melting pots ?

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? Did you ever use a LIBS handheld? Are they better for your needs? Thank you!

thank you, sir.

Would the flux recipe change because you're not having a deal with sulfates/sulfides?

What purity of silver can you expect to get after cupelling until the cupel cannot hold anymore base metals?

I would love to see you do a specific gravity test on that

Would using a electric melting furnace work for refine sliver using led

What furnace and cupellation cups do you use?

Any suggestions. Please help

So for sterling silver it would be super easy just melt it and the copper separates from the silver at 2200 degrees?

Can you reuse the melting cup or is it spent after one use

I use torch (propane +air compressor)

Will this technique work for gold?

Thank you for the video dude, I never did any kind of smelting. So, can you price out how much money you can get from those silver "buttons" you extracted and how much money you spent on the smelting process (heat, lead, other additives, etc.)? Excluding equipment ( because it's the initial investment ).

Cool man!

I have some scrap silver filled epoxy. It is about 75% silver, and was curious if just melting it with some borax would yield pure silver as there is no other metals in it.

Ok you said some of the metals were platinum and maybe gold. So the pyramid isn’t pure silver..it’s a weird alloy?

I have some amalgam containing zinc mercury and silver. I was considering using this method if I can first drive off the mercury (using a still potentially, not sure if it would actually work) do you have any experience with getting rid of mercury?

@aquanano1

2 жыл бұрын

You can do it, if you want, but you need to pay great attention and care to the process. The still needs to be very careful closed and sealed, and the output is to be put under ... let say 5mm of water. Grade your temperature in the process too. Best practice is to wear a full mask with Hg filters fitted, as one mistake may be the last with Hg vapours. You may do without, but then be extra paranoid in your work. Oh, and I assume the still is iron, or stainless steel... :D.

How do you know how much lead to silver ratio to use?

Does it leave any trace lead..in other words could this process be used to purify sterling into 99.9 or better for use make something ingested such as coloidal silver?

Could you cupel sterling silver? I have a few pounds of brazing rod stubs. Guys would throw them on the ground and I would pick them up. Silver content is 15% Would a cupel be a sufficient way to refine this? I’ve watched sreetips use acid but that makes me nervous.

Go with the acid. Do it outside with a mask and fan first time. Vent hoods are a must if you do it inside. Some local refiner will do it for a contract rate. Vent hoods are easy to make with a blower from a evaporative cooler or furnace.

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).
