Extraction of Gold

Cyanide-process The extraction of gold by the cyanide-method is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically. The process was suggested by Mac Arthur and Forrest in 1385, and is based on the well-known solubility of
