An important consideration related to carbon residence time is that the longer the carbon remains in contact with the pulp, the greater the extent of fouling and the greater the detrimental effect on adsorption of gold (Stange, 1999). Total carbon contact time will be influenced by the number of stages, the amount of carbon in each stage, the ...

Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously.

Carbon in pulp（CIP）is one of the methods of gold extraction by cyanidation.It is the process of gold cyanide for carbon adsorption after the cyanide leaching of gold-containing materials is completed. In actual production, most CIP plants will encounter various problems, which not only affect the normal operation of gold beneficiation, also seriously damage the economic benefits of CIP plants.
