Reinventing Copper Extraction With Electricity Mit News

May 01, 2014 Antoine Allanore, the Thomas B. King Assistant Professor of Metallurgy at MIT, wants to simplify copper extraction and eliminate noxious byproducts through electrolysis. If you look at the energy consumption of a copper smelter today, its enormous, Allanore says. They are dependent on electricity already to exist.

Extracting Copper Extracting Copper

Purification Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99 pure copper.
