3. Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.Web

CIL circuit is a process of continuous leaching of gold from ore to liquid and counter-current adsorption of gold from liquid to carbon particles in a series of tanks. The CIL process concentrates gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon. Although the earliest process was in South Africa in 1890, CIP/CIL was first introduced ...Web

The leach may require 24 to 72 hours to complete, and after the leach is completed, the leached slurry is routed to the CIP circuit. In CIP, adsorption of gold and silver onto activated carbon is completed in agitated tanks with interstage screens used to retain the activated carbon within the tank.Web
