You should consider parting the combined beads. Take a bunch of your beads, add some copper, (maybe twice the weight of the gold-silver bead) and remelt it all into one, then flatten the resulting large copperized bead, and dissolve it in Nitric acid. The gold will remain undissolved and can be made into a pure gold bead, the copper and silver will go into solution and after neutralizing the excess acid, the silver can be dropped out of solution with sodium chloride as silver chloride and the precipitate can be turned into a pure silver bead (thus parting the gold and silver).

Hi Chris. Yes I have been thinking about getting into the acid side of things. Makes me a little nervous, but it would be a good addition. One of the things that has held me back is there is really no monetary value in doing it, correct? A PM refiner will pay the same for the gold and silver regardless if it is alloyed or separate is what I have heard. They are only concerned with getting precious metal alloys without a bunch of base metals or black sand. Thanks for the comment and keep watching for more vids :)

Great video. Love your tenacity. Some of your newer viewers may not understand these cupels are special (bone meal, burnt antler or magnesium oxide) and lead is not soluble in them . . . lead oxide is quite soluble in them, and that's why you open smelt them or keep the furnace door ajar. I think your thought process on precious metal loss in crucibles is in the back of all our minds. Very glad you did all that work with the camera running. And, I especially liked your discussion at the end. Thanks for posting.

On and on. All in all, I greatly appreciate your vids!

There's a refiner on KZbin called "Streetips" who chemically refines scrap gold down to 99.99% fine gold! But he only does it with batches that are big enough to be worth it cause it's a long and costly process as far as the amount of chemicals used. It's amazing having the perspective of watching gold being melted down and refined on one hand with heat and on the other hand with chemicals.

I melted 62g of gold dust in a potato with a bit of borax and ended up with an ugly looking 54g nugget. Then I tried to cupel the nugget in a bed of grey cement using a chunk of lead from a heavy wheel weight. The result was a disaster. I got a nice 42g chunk of shiny gold but a lot of gold is scattered throughout the cement. Any suggestions on retrieving my lost gold? Phil

I think most of your lost gold is going to be in the slag itself, in the form of compounds with like sulfur. You'd have likely achieved a much greater amount of gold recovery if you had simply taken all that slag and re-melted it in the presence of an iron bar -- to displace the gold ions with the iron, causing the gold to drop out.

Hi Michael. If there is a lot of iron pull it with a magnet first. The biggest question is how much material are your working with and what are the ratios?

Would you be willing to send me a sample of the material and I could run some tests for you? I would not charge you anything and I would send back all the material when finished. You can send me an email at MBMMLLC@gmail.com and we can discuss if interested. Thanks
