Abstract

The electroleaching of SAR-CHESHMEH copper sulfide concentrate in aqueous sulfuric media has been investigated under the influential parameters as; current density, leaching time, sulfuric acid concentration and temperature. The experiments were carried out in batch conditions and static bed status. Based on the illustrated results, concentration of copper in leaching solution increases strongly when electric current is applied. At the above-mentioned conditions the concentration of copper decreased while the electrical current is increased toward the maximum. On the other hand, the concentration of Fe2+ in leach liquor increases with increasing the current density. So, the irregular increasing of current density is not convenient to electroleaching of copper concentrate. The results showed that both anodic and cathodic reactions during the leaching process caused the copper concentration decreases at the long period of times, but iron concentration increases rapidly. It is also suggested that the deposition of copper on cathode surface during the leaching process "as a reduction reaction" causes the decreasing of the copper concentration in the solution. Decomposition of copper sulfides is an endothermic reaction, so the copper concentration of solution increases with increasing the temperature up to 80°c. increasing the temperature from 60°C to 80°C decreases the iron extraction during the process.
