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.
