Abstract
The cells used in the electrowinning experiments were compared in terms of cell voltage, pH and copper concentration. The results showed that it is possible to remove copper successfully from the mine waters with a high degree of electrowinning-higher than 92% and with a satisfactorily average current efficiency (>60%). Depending on the process time and the applied current, a final copper concentration less than 0.1 g dmâ3 was achieved. The specific energy consumption was approximately 7 kWh kgâ1 of deposited copper. A dense copper deposit was obtained when a three-dimensional electrode was used.
