How Copper Affects Cyanidation & Leaching
CuSO4 + 2 NaCN = Cu (CN)2 + Na2SO4. Cupric cyanide, when precipitated thus, is greenish yellow in color. On standing for a short time, or on heating, the precipitate changes to white flocculent cuprous cyanide. This is due to the decomposition of the unstable cupric cyanide into cuprous cyanide and cyanogen: 2 Cu (CN)2 = 2 CuCN + …

In Situ Leaching – Hydrometallurgy
Gold heap leaching began around 1969. Most of the world's hydrometallurgical copper production is obtained from heap leaching operations. The biggest facility in the world is in Chile and produced 145,000 tonnes of copper in 2010. A gold leach with as little as 0.5 g Au/t ore (0.5 ppm!) can be profitable.
