The Management of Cyanide in Gold Extraction - Mining Focus

Gold mining operations use very dilute solutions of sodium cyanide (NaCN), typically in the range of 0 01 and 0 05 cyanide (100 to 500 parts per million) The process of metal dissolution is called leaching The sodium cyanide dissolves in water where, under mildly oxidizing conditions, it dissolves the gold contained in
