The first patents for metal electrorefining, were for copper and were granted to James Elkington in England in 1865. The first copper refinery was built in Newark by Balbach Smelting and Refining Company in 1883. Early electrorefineries had difficulty producing firm cathode deposits of high purity copper.

Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably). Copper ores are usually copper oxides ...

needed to drive the electrochemical reactions. For industrial copper and zinc electrowinning, the median specific electrical energy consumptions are 2.0 and 3.0 kWh kg−1, respectively [3, 4]. This electrical energy consumption accounts for 80% of the total energy consumed in copper electrowinning [5] and 94% in zinc electrowinning [6].
