Metal recovery or concentration by adsorption on activated carbon has been the dominant process for gold extraction after leaching by cyanide in aerated alkaline slurry. The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carbon-in-pulp (CIP) and the carbon-in-leach (CIL) processes, have been …
The first task is to measure the quantity of carbon in the various process stages. In carbon columns (CC) or strip vessels where only carbon is present, a direct volumetric measurement is possible. In carbon-in-pulp (CIP) or carbon-in-leach (CIL) systems it is necessary to obtain a sample from the agitated mix of carbon and pulp.

CN- is required to leach gold and thus at decreasing pH's the quantity of CN- decreases due to the formation of HCN as pointed out above. Thus, the gold leach reaction can become cyanide limited if the CN- concentration gets too low - can compensate by having higher cyanide addition but also get higher HCN and hence HCN loss!
