Gold CIP/CIL Processing Plant
The gold cyanidation process, also known as gold CIL (Carbon in Leach) or CIP (Carbon in Pulp), is a hydrometallurgical technique used to extract gold from ore by converting the gold into a water-soluble coordination complex. This method is the most widely used leaching process for gold extraction, accounting for approximately 90% of global gold production.
DASEN MINING boasts 30 years of experience in producing gold CIL/CIP equipment and managing EPC (Engineering, Procurement, and Construction) projects. We have completed over 60 projects worldwide.
Gold Cyanidation Leaching Processing Flowsheet
- Step 1： Pulp impurity removal
Before the 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.
- Step 2 :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 a carbon extraction sieve.
- Step 3 :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.
- Step 4:Smelt
After simple pickling and removal of impurities, the obtained gold mud can directly smelt gold ingots.
