Abstract
A process for electrowinning of copper from leach solutions 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 efficiency and consequently decreasing the power consumption.
