CIP CIL CIC

CIP and CIL processes recover gold directly from ore pulps or slurries containing up to 55% solids using activated carbon, while CIC treats solutions from heap leaching. CIP and CIL generally have lower capital costs than the traditional Merrill Crowe zinc cementation process but may have higher operating costs, especially for slow-leaching ores.
