Gold CIP and CIL process optimization in a capital

Several tools have been developed over the years to assist in achieving maximum value from the gold recovery process including several models that can predict the leaching and adsorption of Au in the CIP or CIL process These models are predominantly used by design houses to design and size the plant and in most cases this is where the usage of these models stops The reason for this is not
