Gold Ore Processing. Carbon-in-pulp (CIP) consists of cyanide leaching and then absorption of gold from ore, which is considered a simple and cheap process. Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution. CIP plants are similar to Carbon-in-leach plants.
