Gold CIL CIP Gold Leaching Process Explained CCD

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a goldplex. The goldplex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon in leach. This is a gold extraction process called cyanidation where carbon is added to
