Inquire NowThe dissolution of gold through cyanidation, either Carbon in Pulp (CIP) or Carbon in Leach (CIL), is an oxidizing reaction. Generally added oxygen, in the form of dissolved oxygen in solution, improves the process as the rate of gold dissolution is directly proportional to the amount of dissolved oxygen in solution.
