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 gold cyanide complex The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon CIL stands for carboninleach This is a gold extraction process called cyanidation where carbon is added toAfrican gold plant These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation The ore is first reduced in size (typically 80% passing 75µm) to ensure that all nonrefractory gold is readily accessible for cyanide leaching There are several variations of comminution circuits used in theThe process design of gold leaching and carboninpulp
