(1984a) developed one of the first CIP/CIL process models. The model assumes that the flow of pulp and carbon are counter-current but continuous and steady-state conditions are achieved such that the concentration of gold in solution remains constant at each stage of the circuit. All tanks are assumed to be perfectly mixed.

Gold CIP/CIL Plant Introduction CIL (Carbon In Leach) leaching process, that is, carbon leaching gold extraction, is a process of adding activated carbon to the pulp and leaching and adsorbing gold at the same time, which simplifies the CIP (Carbon In Pulp) process.
