3. Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.

that are packed with carbon. The process is known as carbon-in-columns (CIC). For mill, agitated-tank leaching operations, gold is extracted directly from the leached pulp in either a carbon-in-leach (CIL), or a carbon-in-pulp (CIP) plant. In both these cases, the coarse granules of activated carbon are mechanically mixed with the
Carbon in pulp - Wikipedia
Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.
