Gold cyanidation - Wikipedia
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.

Cyanide Leaching Chemistry & Gold Cyanidation
Compare Cyanide VS Thiosulphate gold Leaching. No two ores are exactly alike. Therefore, it is practically impossible to predict how an ore will act during cyanidation, although broad generalizations can sometimes be made. In general, therefore, every ore presents its own problems in cyanidation. One of the most frequent sources of trouble, in cyanidation is the presence of copper minerals in ...
