Activated carbon is a highly porous material with distinct adsorptive properties. Gold complexes with either
chloride or cyanide are strongly adsorbed by activated carbon. Gold recovery from solution by granular, begins by
loading, or adsorbing the gold onto the activated carbon, which is accomplished in the carbon-in-leach (CIL) circuit.
The CIL activated carbon system involves adding the carbon to the ore slurry in leaching tanks. The carbon adsorbs
the gold from the solution as cyanidation of the ore proceeds. After adsorbtion, the loaded carbon is sent to the
carbon stripping circuit.
