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 Leach (CIL) Production Monitoring System It is a concern to know that the cost of retrieving the gold ore from deep below the surface of the ground, bring the ore body and waste material to the surface, crush and mill the ore to a fine slurry in order to process and recover the gold. These initial costs (at a guess)
to the use of Dowex-Minix for the recovery of gold from clarified, pregnant leach liquors. LTA Process Engineering approached Mintek to evaluate resin-in-solution (RIS) for the recovery of gold from a milling-in-cyanide operation at a Witwatersrand gold mine. A small amount of gold was leached during the milling process, so that this milling-in
Carbon Adsorption Theory After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material.
