Extraction Of Gold

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 gold in potassium,extraction of gold and it processing,amalgamation is the gold extraction method most often used in artisanal, or small-scale, gold mining. although amalgamation is a simple and effective way to isolate gold, it results in the release of mercury, a toxic substance, into the environment.
