leaching agitator for gold cil plant

Gold CIL & CIP Gold Leaching Process Explained CCD

Mar 17, 2017 ... Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex 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...
