[QUOTE="Dr4gul3, post: 156196, member: 5164"] not much in the way of acids will dissolve gold. a mix of 3 parts hydrochloric and 2 parts Nitric will dissolve pretty much anything though. what KarlS suggested sounds pretty good idea. I could ask some of my old refinery buddys to see what would dissolve the lead easily if you want, they might even give me some live examples haha they have plenty of lead floating around. that said, you could also try Oxidizing the Lead, if you get the molten lead above 900 degrees it should start oxidizing, that will oxidize all of the base metals and lead, and leave only precious metals. and to help the process you can melt it on a marborite crucible or cupel which soaks up the molten lead pretty easily.
