Leaching & Adsorption Resource Book

Minerals that cause excessive consumption of cyanide are called cyanocides. Examples include copper, nickel, iron and sulphide minerals. If they are present in the ore, extra cyanide must be added which can add considerably to the cost of leaching the gold. Other minerals, such as arsenic can react with the oxygen and slow the rate of gold
