How to Distinguish Between CIP and CIL?
CIP (Carbon In Pulp), that is, gold extraction by carbon pulp method. It is a non-filtering cyanide carbon slurry process that directly uses activated carbon to absorb and recover gold from cyanide pulp. It mainly includes seven operation stages: preparation of leaching pulp, cyanide leaching, activated carbon adsorption, gold-loaded carbon desorption, gold mud obtained by electric shock, recirculation of gold-removed carbon, and treatment of leaching pulp.
CIL (Carbon In Leach), that is, carbon leaching method for gold extraction. It is a process in which activated carbon is added to ore pulp while leaching and adsorption are carried out at the same time. Simplifies the leaching and cyanidation of the CIP process.

Summary
Currently, globally, the cyanidation carbon leaching process has gradually become the preferred process for most gold mine owners when processing gold, because it has better recovery rates and is more inclusive of the properties of different gold mines. However, considering the cost, many gold mine owners prefer to use small processing capacity for ore processing first, and then expand the processing capacity when good results can be obtained.
