CIP Activated Carbon in Pulp Gold Processing

People also ask what the difference between carbon in leach and carbon in pulp is. The carbon-in-place (CIP) process is to first perform cyanide leaching, and then add activated carbon to the slurry to adsorb gold. The carbon-in-place (CIL) process is to add activated carbon to the leaching tank, and leaching and adsorption are carried out ...

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 ...
