Detoxification of Cyanide in a Gold Processing Plant

Abstract. In laboratory experiments, cyanide in waste water from the Muteh gold mine in Iran was oxidized by sodium and calcium hypochlorite to cyanate (CNO ), which is 1,000 times less environmentally hazardous than cyanide.Experiments were conducted using waste water containing 270 mg/L cyanide over a pH range of 613 and temperatures between 25 and 50176;C.
