THE VALUE OF - Calgon Carbon

The pulp is transferred to a series of adsorber tanks containing activated carbon, which mixes with the leached pulp and flows countercurrent to the pulp in a series of tanks. The gold-bearing activated carbon is separated from the pulp by a mesh screen that blocks the carbon from passing through, while the smaller pulp particles are filtered away.

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 (carbon-in-pulp), CIL (carbon-in-leach) and CIC (carbon-in-columns). More recently, SGS has lead the gold processing industry with the development of resin-based technologies.
