Dear forum members,
I have a small workshop at industrial zone. There is 15 tons about Cu and CuO mixed powder waste. (This waste content total 3~3.5 kg Au, 10.5~11 kg Ag, 550 gr Pd and 110 gr Pt.)
No electrolysis equipment. I think about the process in a simple and practical way.
First, the solution with 1: 1 distilled water: concentrated nitric acid. Copper, silver and palladium will dissolve. Gold and platinum will remain in the filter. AgNo3+Cu = Cu(No3)2 + Ag. If I add pure copper to nitrate solution (Cu+Ag+Pd) Ag and Pd drop?
Also, Au and Pt aqua regia dissolve OK. How I can selectively separate them?
Your help will be greatly appreciated.
Sorry bad English.
Regards,
Mehmet
