ground. The leaching chemical solution for gold and silver is commonly sodium cyanide. In dump leaching, which is used primarily for low-grade copper ore, the material to be treated is placed on unlined foundations (i.e., directly on the ground). The leaching chemical solution typically is sulfuric acid but sometimes is water.

It reduces the volume of cyanide required to leach the gold or silver. In addition, hydrogen cyanide is highly toxic to people. So, the few dollars spent on adding a cheap calcium oxide to the ore or solution, prior to leaching is worth the money spent.
