[QUOTE="Heatho, post: 142974, member: 487"] I guess this is why Mercury was so popular, it made it easy to capture the Gold you can't see, same with heap leaching and Cyanide, these 2 would have been and probably still are the the cheapest ways to do this for large operations. Fire assay as Karl did is spot on but time consuming and maybe expensive, great for knowing what is in it though. Once you have your Gold in the Lead tip then Cupellation in a cupel/crucible is the way to separate the Lead and Gold. I read a lot about all this a while back but have forgotten half of it. There is a yank forum totally dedicated to this stuff, can't remember the name of that either ATM, will see if I can find it again. [/QUOTE]
