Cyanide leaching of gold is an important industrial solvent gold, most gold producers using the hydrogenation method, and Cyanide is highly toxic and easy to be both a degradation of specialty chemicals. Cyanide comes from a high concentration of industrial wastewater containing cyanide, mainly electroplating wastewater, waste gas cleaning and cooling water cyanide gold extraction, coke oven and blast furnace, some chemical and mineral processing sewage effluent, synthetic rubber, fibers and dyes industry. 

Features:
