 · The experiments demonstrate that the porphyry ore, when treated by a hydroelectrolytic process, will yield its entire copper contents as a good grade of hode copper. It is therefore hoped that by using a hydroelectrolytic method, lowergrade copper porphyry deposits may be worked than formerly could be worked by methods of concentration followed by smelting.

Electrorefinery is a process which uses electrolysis to increase the purity and quality of copper and many other metals. In the copper electrorefining cell, there are two electrodes immersed in an aqueous solution (figure 2). One is the impure copper anode and other is hode blank usually made of steel where the copper will deposit.
