Hey Everyone, been away for a while. I, as some know, am in Ontario. I'm not in a position to buy/nor make nitric acid. I'm working with electronics (can't afford anything more profitable), I've been brainstorming and came up with an idea that may or may not work. Here are the chemicals I have available; HCl, H2SO4, bleach, lye, ammonia, hydrogen peroxide as well as SMB. Every process that I will be doing will be utilizing only HCl with either bleach or H2O2 as the oxidizer.
Now I know that when we dissolve the solder in the boards using HCl prior to any kind of recover, there will be tin, lead and potentially gold and silver dissolved within the lead. I believe, that once the HCl is exhausted the gold will fall out as a black powder and the silver/lead will precipitate as a white powder, the tin should stay in solution if I'm not mistaken.
I forgot to mention, I'll have at least 4 5-gal buckets, one of Cu2Cl, one for stock w/ copper, one for waste w/ iron and one for cleaning waste with lye before discarding.
I'm not exactly sure which waste bucket the exhausted HCl from the solder removal should go into, I'm think the one with copper just in case there are any more valuables in solution.
Now comes the question mentioned in the subject. Since I am working primarily with AP (Cu2Cl) would it be possible for anything that I know has silver (or gold) in it, to melt it all down with an excess of copper, corn flake it and use Cu2Cl to dissolve away the copper and leave the silver as silver chloride?
I'm planning on using a Crockpot filled with water as a water bath and Pawnbroker Bob's AB Train to get rid of fumes, etc.
Would my hairbrained idea work? I do in the future plan on building a gold stripping cell, but that is on the back burner for now. Too many things going on in my life to work on that. Anyway thanks.
