OPTIMIZING THE OPERATING CONDITIONS OF GOLD
The final gold product of Tau Lekoa mine has a low fineness. This is caused by high concentration of bases metals in the reefs. Some of these base metals together with gold are leached with cyanide and are loaded into carbon. If not adequately controlled, they may elute with gold and contaminate the final product in the electrowinning process.

Cyanide Leaching Mining SGS
More recently, SGS has lead the gold processing industry with the development of resinbased technologies. In this case, the gold is adsorbed onto the synthetic resin particles rather than activated carbon. This process is more efficient, easier to control and more robust than carbonbased technologies. Variations on this process include:

Elution and Carbon Reactivation Resource book
During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.
