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.

CIP (carbon-in-Pulp) and CIL (Carbon-In-Leach) are two commonly used gold mineral processing processes, both of which use activated Carbon to adsorb gold, so as to achieve gold extraction. The CIP process is to add activated carbon directly to the pulp, while the CIL process is to inject the pulp into the activated carbon bed.
