CIP (Carbon In Pulp) is a non-filtered carbon cyanide pulp process that directly uses activated carbon to absorb and recover gold from cyanide pulp. It mainly includes seven operation stages: preparation of leached pulp, cyanide leaching, activated carbon adsorption, gold-loaded carbon desorption, gold mud obtained by electric shock, gold-removed carbon recycling, and treatment of leached pulp.
• The main steps: are pulp impurity removal, leaching and adsorption, desorption electrolysis, and smelting.
• Application: flotation of gold concentrate or amalgam, gravity separation tailings, muddy oxidized ore.
CIL (Carbon In Leach) is a carbon leaching process. It is a process of adding activated carbon to the pulp and leaching and adsorption at the same time. It simplifies the leaching and cyanidation of the CIP process.
• Main steps: crushing, grinding, leaching, desorption electrolysis, tailings dehydration
• Advantages: low investment, low cost, short infrastructure time, few production links, and small footprint.
