Free gold can be rapidly recovered in high amounts using gravity concentration methods. Traditionally, simply exploiting the high specific gravity of free gold for recovery required little energy and was profit-generating. Today, however, more milling energy is consumed due to the change in mineralogy of gold .
The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning. Gold specific resins can also be used in place of activated carbon, or where selective separation of gold from copper or other dissolved metals is required.
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 cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in .
