Gold Mining Operation: 10 - 30 years. The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold.

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.
