OverviewGold ore processingHistoryStatisticsMethodsBusinessAdverse effects and responsesSafety

Cyanide extraction of gold is the dominant method for obtaining gold. Finely ground rock is treated with a solution of sodium cyanide. The extract is absorbed onto carbon. The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide. Gold cyanide is then converted to relatively pure gold by a variety of methods.
