Cyanide Leaching | Mining | SGS

Activated carbon effectively removes the gold from the cyanide, as the gold is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carboninpulp), CIL (carboninleach) and CIC (carbonincolumns). More recently, SGS has lead the gold processing industry with the development of resinbased technologies.

carbon in pulp process

A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.

Gold CIL CIP Gold Leaching Process Explained CCD

CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carboninpulp process.

Carbon in Pulp Plant

The carbon advances countercurrently to the pulp. The carbon is maintained in suspension in the pulp by an internal airlift and mechanical agitation of the pulp, either with rakes or with axial flow propellers. This last arrangement is preferred because in case of power outages the pulp can be easily repulped after the power is restored.
