Gold Cyanidation Process
Eisner's equation is generally accepted as expressing the action of gold in dilute cyanide solutions; 4 Au+ 8 KCN + O2 + 2H2O = 4 KAu (CN)2 + 4 KOH. Thus, when fresh surfaces of gold are exposed to the action of cyanide in an aqueous solution containing free oxygen, a gold cyanide compound will be formed and a hydroxide (alkaline).
