In obtaining gold from vein ore, the ore is first crushed in rod or ball mills. This process reduces the ore to a powdery substance from which the gold can be extracted by amalgamation with mercury or by placer procedures. About 70% is recovered at this point. The remainder is dissolved in dilute solutions of sodium cyanide or calcium cyanide.
