Copper electrometallurgy

The metals considered by the NCST are aluminum, copper, lead, zinc, and magnesium. With a view toward the demand for these metals and their alloys, the plans proposed by the NCST panel include (I) facilities for hydrometallurgy and electrometallurgy, (2) production of magnesium, and (3) production of high-strength aluminum and magnesium alloys for the defense and space industries.

Electrometallurgy, which utilizes electrochemistry to reduce and refine metals, is examined with attention to sodium, aluminum, and copper. 

Section 23.4 Electrometallurgy is tire use of electrolytic methods to prepare or purify a metallic element. Sodium is prepared by electrolysis of molten NaCl in a Downs cell. Aluminum is obtained in the Hall process by electrolysis of AI2O3 in molten cryolite (NagAlFg). Copper is purified by electrolysis of aqueous copper sulfate solution using anodes composed of impure copper.
