     · Before the gold is plated out or zinc''d out (see my procedure above), you would have to dissolve it in either a sodium cyanide or potassium cyanide solution. In both plating and zinc-ing, you should use a little extra cyanide, maybe about 15 g/l extra, beyond what it takes to dissolve the AuCN.
