Recovering Cyanide From Gold Plant Tailings
form in which it exists in gold plants, to hydrocyanic gas, HCN. The negative perception of this highly toxic gas, and concerns about the ability of the mining industry to handle it safely in a processing plant, has probably been the single largest impediment to the implementation of cyanide recovery technology in the gold industry. In thisDetoxification of Cyanide in a Gold Processing Plant,,Nov 16, 2007· 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 6–13 and temperatures between 25 and 50°C.Gold Extraction, Gold Cyanide, Gold Manufacturing Process,,Taking the gold cyanidation plant with processing capacity of 100000 tons per year and gold grade of 7.5 g/t as an example, gold CIL process can save the investment cost of $486000 than the CIP process, reduce the capital backlog of $201700, save and recycle capital of $675100 in advance excluding the cost of activated carbon.
