Carbon Adsorption Theory After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material.

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.

Activated carbon can be manufactured from wood, nuts shells, coal, petroleum coke and a variety of organic products. Coconut shell carbon is preferred because of its commendable durability and high adsorption capability for gold and silver cyanide [5]. Other modifications include Carbon-in-Leach (CIL) and Carbon-in-Column (CIC).
