Technical Note Feasibility of cyanide elimination …

cyanide was not toxic when added to the irrigation water at up to 125mg KCN/l (50mg CN/l). In a degradation test, cyanide was efficiently degraded by sorghum roots and leaves. Cyanide elimination using plants seems to be a feasible option for gold and silver mine waste and wastewater. Theoretical estimates indicate that a large area of land is ...

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).
