The pretreated concentrates and in some cases along with the flotation tailing, are transferred to the carbon in pulp (CIP) or carbon in leach (CIL) processes where gold is dissolved and adsorbed onto the activated carbon (Marsden and House, 2006; Staunton, 2005). The gold sorption efficiency onto the activated carbon is affected by a number of ...

A semi-empirical model was developed to represent a carbon in leach/carbon in pulp (CIL/CIP) circuit for recovery of gold and silver. The model uses a simple two rate representation of the leaching kinetics. Parameters for the leaching kinetics may be obtained by sampling the feed to a circuit and the tailings from each tank and …

Activated carbon is widely used for gold recovery from cyanide leach liquors via carbon-in-leach (CIL) or carbon-in-pulp (CIP) technology. From all the base metals cyanide complexes typically present together with gold in the leach liquor, only copper, and to a lesser extent nickel, are loaded onto activated carbon(6).
