About Gold CIP. Gold CIP is one of the methods of gold extraction by cyanidation. It is a carbon adsorption process of monovalent gold cyanide [KAu (CN)2] after the cyanide leaching of gold-bearing materials. CIP usually applies in flotation gold concentrate, high argillaceous oxidized gold deposit, mercury mixing, and gravity separation tailings.
