Electrolytic Recovery of Copper and Zinc from Brass.

copper and zincmercial brass by an electrolytic method. Such a method would produce metals which would be equivalent to Xinhai metals in purity. Both Barker and Swank found that such a recovery was possible with brasses containing only copper and zinc but that very small amounts of lead would interfere with the dis solution of the anode.

Copper Mining and Extraction Sulfide Ores

The electrolytic refining of copper produces the high quality, high purity copper required by industry. Even the best chemical method cannot remove all the impurities from the copper, but with electrolytic refining it is possible to produce 99.99 pure copper. Copper cathodes are hung between anodes.
