Electrowinning Gold Ore

Electrowinning Gold Processing Rigaku Global Website

After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as Carbon-in-Pulp CIP, Carbon-in-Leach CIL, or Carbon Column CC. Once absorbed, the gold is stripped from the Carbon and the impregnated stripping solution fed into the electrowinning process where the gold is recovered by electrolysis.
