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. Carbon in Pulp - JXSC Mining,Carbon in pulp process. Gold Carbon-in-pulp (CIP) production is the sequential leach, then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution.The process design of gold leaching and carbon-in-pulp,,of concentration 10–25 grams of carbon per litre of pulp (0.5 to 1.2% by volume carbon). The carbon is retained in each reactor by means of screens having an aperture of 0.6–0.8 mm which allows pulp to flow through and out of the reactor whilst retaining the carbon in the reactor. The gold aurocyanide complex in the aqueous phase is
