The process design of gold leaching and carbon-in-pulp ...

The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1 500. A portion of the loaded carbon is periodically removed from the first ...

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.
