Process of Electrowinning of Gold - cnlitereagent

2019-12-3  Process of electrowinning of gold, also called electric extraction, is a process of recovering gold by desorption electrolysis of gold loaded carbon under high temperature and high pressure conditions. It is an important part in the gold cyanidation process. Why is this process widely used in mineral processing plants?

2021-10-25  After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), or Carbon Column (CC). Once absorbed, the gold is stripped from the Carbon and the impregnated stripping solution fed into the electrowinning process where the gold is recovered by electrolysis.
