Modeling and optimization of Carbon in leach (CIL) circuit …
Pulp density can be a major factor affecting the results for plant design purposes also consumes cyanide, so its effect has to be accounted for in the case of carbon-in-leach (CIL) or carbon-in-pulp important that the scale-up of cyanide consumption from laboratory to plant be representative. The traditional method leach tails.

In a CIP plant, leaching is complete before the first adsorption tank, and gold is then recovered from the leached pulp in a series of (typically) 4–10 dedicated carbon adsorption tanks. In a CIL plant, the carbon is added directly into the leach tanks, with the claimed advantage of lowering capital costs by eliminating the CIP adsorption tanks.
