Cyanide has long been used for the recovery of gold from gold ores, by leaching of the ore. In a gold leach, the presence of oxygen is essential, the leach is for at least about 24 to 48 hours, and copper has been regarded as a cyanicide, that is, cyanide is consumed in the process, resulting in a loss of cyanide, and increasing costs.
