The gold mining industries are among the largest consumers of cyanide due to its high affinity with gold. After the precious metal has been extracted from ore, cyanides are discharged as effluents and as solid mine tailings.
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 cyanidation where carbon is added to the leach tanks (or reaction vessel) so that ...

Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant.
Extracting gold from ore is a poisonous business. The most common method is cyanide leaching, where cyanide salts in solution are used to suck the gold out from its ore.
The equipment required for a cyanide plant will vary considerably with the value of the ore, the settling rate, the chemical composition of the ore, the hardness, and the degree of grinding required, as well as other important factors.
