Currently, the most common source of copper ore is the mineral chalcopyrite (CuFeS 2 ), which accounts for about 50% of copper production. The focus of this article is on the process of copper extr...

The anode sludges from copper-refining cells provide one fourth of U.S. silver production and about one eighth of U.S. gold production.

The final step is a process called electrorefining. This is done by electrolysis where the copper anodes from the smelter become positive electrodes and thin, three-foot square sheets of pure copper are used as negative electrodes.

Still another object of the invention is the provision of a copper-refining process which, in combination with conventional leaching technology, is adapted to the winning of copper from its oxide ores without electrolytic or high-pressure hydrometallurgical unit operations.

In the electrolytic copper refining process, it is well understood by those of ordinary skill in the art that a desideratum in current distribution in a tank or cell is to have no anode to cathode short circuits, all cathodes carrying equal currents, and no non-current-carrying cathodes or anodes.
