3). Thus, the gold particles are in electrical contact with that electrode. Since secondary electrowinning may also be carried out simultaneously in that cell, the gold from both sources is effectively combined at the cathode. However, initially the EWEF cell was used on its own to electrowin gold from original and diluted eluate solutions.

Electrowinning (or electroextraction) is a process of whereby metals, such as gold, silver and copper,are recovered from a solution by means of electrolytic chemical reaction. This takes place when an electric current is passed through the solution. During the process, electrons from the electric current chemically reduce the metal ions, to form a solid metal …

The purpose of the present invention is to make it possible: to, before gold is eluted, effectively remove copper, iron, and sulfur, which are impurities from the standpoint of gold recovery, from activated carbon on which gold has been adsorbed; and to efficiently elute the gold. Provided is a method for eluting gold (Au) from activated carbon on which at least sulfur (S) and Au have been ...

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.
