"Carbon-in-leach (CIL) and carbon-in-pulp (CIP) processes utilize activated carbon to adsorb solubilized gold for recovery. Due to carbon attrition and non-ideal carbon management, however, some of the gold is lost in carbon fines and to the solution. The carbon attrition mechanism inside CIL/CIP reactors is mainly abrasion-related. This …

Carbon adsorption. The cyanide pulp enters the stirring adsorption tank (carbon slurry tank). Add carbon to the leaching tank, and the carbon adsorbs the gold in the pulp to become gold-loaded carbon. After the adsorption is completed, the carbon and the pulp are separated by a carbon extraction screen. Gold-loaded carbon desorption

shell carbon was unclear (Tsuchida and Muir, 1986). Similarly, there is no consensus on the factors which determine the carbon- gold adsorption reactivity in a CIP plant and the selection of carbons for use in CIP plants has no broad scientific basis. We have therefore studied the fundamental aspects of gold adsorption on activated carbon.
