ELECTROWINNING OF COPPER IN PRESENCE OF HIGH CONCENTRATION OF IRON ABSTRACT OF THE DISCLOSURE: A process for electrowinning of copper from leach solu- tions containing a high concentration of iron in the range of about 5 to 40 gpl, is disclosed. The process consists in applying direct current through the solution and periodically reversing the polarity of such current to obtain a solution having a low ferric ion concentration, thereby increasing the operating current effi- ciency and consequently decreasing the power consumption.
