Carbon-in-pulp
For example, carbon and gold inventory is higher for a CIL operation compared to a typical CIP operation (Nicol et al., 1984b). As a consequence of the greater carbon inventory, CIL plants experience increased carbon breakage, representing increased loss of carbon and gold. There is also a greater risk of carbon fouling. Stange …

The development of regrind–flotation pre-treatment of the CIL …
1. Introduction. In porphyry/skarn copper–gold flotation plants gold recovery is often well below copper recovery [1].With liberated and copper-associated gold readily recovered in the flotation stage, this recovery difference is often due in part to operating strategies that require rejection of gold-bearing iron sulphide gangue minerals in order to …
Liquid–Solid Separation in Gold Processing
The flowsheets in Figure 18.1, Figure 18.2, Figure 18.3 illustrate how liquid–solid separation fits into carbon-in-leach (CIL), carbon-in-pulp (CIP), and Merrill–Crowe circuits, respectively. In addition, heap leach, column leach, and gravity circuits also need to have liquids separated from solids, and there are many variations of …
