Gold CIP and CIL process optimization in a capital constraint
Introduction. The well-known carbon-in-pulp (CIP) and carbon-in-leach (CIL) gold recovery processes are fairly robust. Considering the constantly changing characteristics of run-of-mine (ROM) ore, a robust process is in general a great advantage for a mineral processing plant. The disadvantage, however, is that because less input is required ...
