Gold CIL CIP Gold Leaching Process Explained CCD

CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process.

Carbon in pulp - Wikipedia

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

Activated Carbon for Gold Recovery Puragen Activated Carbons

Gold Recovery Process For gold recovery, water and a cyanide such as calcium cyanide, sodium cyanide, or potassium cyanide, are added to ore or scraps to form a slurry. The gold will leach out and mix with the cyanide into a solution. Activated carbon is then used to separate and store the gold, which is removed as the final step of the process.
