It then flows into the CIL, (Carbon In Leach), tanks where cyanide, oxygen and activated carbon are added. The oxygen and cyanide dissolve the gold, which is then absorbed onto the activated carbon. The carbon loaded with the gold is screened out of the slurry and processed further to make gold bars.

Modeling and optimization of Carbon in leach (CIL) circuit

Modeling and optimization of Carbon in leach (CIL) circuit

Carbon in leach (CIL) is an important step in gold processing that involves simultaneous adsorption and leaching. While the mechanism of leaching and adsorption are well known, the effect of different operating and design parameters on the dynamics and performance of CIL circuit are not yet studied.

The process design of gold leaching and carbon in pulp

The process design of gold leaching and carbon in pulp

Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.511 to ensure minimum loss of cyanide as hydrogen cyanide.

Carbon Adsorption Kinetics Gold is typically recovered from solution by adsorption on to activated carbon in a carbon in pulp (CIP) or carbon in leach (CIL) circuit. The kinetics of this adsorption process is slow, so industrial practice is to load the carbon far short of the equilibrium loading potential.
