The process design of gold leaching and carbon-in-pulp ...

2009-8-27  The carbon-in-leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as only one set of agitators for both leaching and
