The process involves a chemical reaction between cyanide and the minute particles of gold found within ore, forming a solubilized gold-cyanide solution. From this solution, gold is later recovered, often by carbon adsorption. This technique benefits low-grade ores, where traditional methods would prove economically unviable.

Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. In the absorption stage, this solution flows through several agitated tanks containing activated carbon.
Elution and electrowinning pilot plant is the key equipment for the gold extraction by the method of cyanidation, CIP or CIL. It will desorp gold from activated carbon to concentrated gold solution. Electrowinning is a process used to recover metals gold from concentrated solutions. It is an ideal pilot equipment for gold extraction. Features:
