What is Gold CIP/CIL Processing Plant ?
- Pulp impurity removal
Before adsorption of cyanide pulp, wood chips and other impurities shall be treated to prevent gold and activated carbon in wood chips adsorption pulp from mixing into rich carbon, and prevent wood chips from blocking the carbon-separation screen.
- Leaching and adsorption
Add activated carbon into the leaching tank. The activated carbon adsorbs the gold in the pulp to become gold loaded carbon. After adsorption, the activated carbon and pulp are separated by carbon extraction sieve.
- Desorption electrolysis
Gold loaded carbon can be rapidly desorbed and electrolyzed into gold mud and lean carbon under the conditions of high temperature and high pressure in a closed system.
After simple pickling and removal of impurities, the obtained gold mud can directly smelt gold ingots.
What is the difference between CIP and CIL?
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.
