Activated carbon reduces fines formation and increases yield. A major use of activated carbon in mining is in gold recovery, where granular activated carbon (GAC) is used for adsorption of the gold-cyanide complex in carbon-in-pulp (CIP) and carbon-in-leach (CIL) systems, or in carbon-in-column (CIC) systems after a heap leach operation carbon.
