Carbon-In-Pulp

With carbon-in-pulp, the ore is finely ground and the gold is solubilised using a cyanide leach in a series of tanks. The granular activated carbon is added to the leached slurry, where the carbon adsorbs the gold from the slurry solution and is then removed from the slurry by coarse screening. Often a series of five or six agitated tanks are ...

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

CIP History – Denver Mineral Engineers

The ore-carbon slurry flowed out of one tank and entered the open end of the revolving screen in the next tank. Ore pulp passed through the screen, which detained the carbon on the screen surface. As the trommel rotated, carbon was elevated. The water sprays directed such carbon to a launder for return to the originating tank during normal ...

Carbon in pulp

Carbon in Pulp (CIP) is a technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process, a gold extraction technique.. Introduced in 1985, 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.

Gold CIP Processing Plant, Gold Carbon-in-Pulp Process

The gold CIP (Carbon-in-Pulp) processing is widely used to extract gold from ore. It mainly involves using activated carbon to adsorb gold from a cyanide solution, then eluting and regenerating the carbon for reuse. It is mainly suitable for beneficiating gold-containing oxidized ore with high slime content and containing carbon ore.
