Cyanide, widely used in chemical and mining industry, is one of the most important environmental issues due to the acutely toxic properties of many cyanide compounds to humans and aquatic life. This research is aimed at investigating a feasible and economical technique for the detoxification of cyanide from tailing wastewater of Muteh gold mine. Cyanide detoxification was achieved through the oxidation of cyanide by using calcium and sodium hypochlorite using various concentrations of oxidant solutions at alkaline pH levels and temperatures between 12-65?C Cyanide titrated using Rhodanine solution and silver Nitrate. Cyanide concentration in waste water was measured 270 mg/lit. Removal was achieved at optimum pH of 12.3 for both solutions. However, at higher temperatures, cyanide removed completely at this pH level. Optimum Doses of calcium and sodium hypochlorite for perfect cyanide removing, were 1.43 and 8.64 gr/lit, respectively.
