aluminum smelting and electrolysis

Chapter 2. Production and Processing of Aluminum

The electrolysis plant—the aluminum smelter—needs large amounts of electrical energy. Therefore, besides good bulk transport facilities, abundant inexpensive electric power is essential. Because hydroelectric power is a relatively inexpensive and clean source of energy, aluminum smelters are mostly built in countries with readily avail- able hydroelectric power, such as Canada, Norway ...

The Aluminum Smelting Process How the Hall-Héroult Process works... Inert Anode Technology . As we have seen, electric current passes through the molten bath carried by carbon anodes immersed in it. Carbon anodes not only are used to carry the current, but also participate in the alumina reduction chemical reaction: On a practical side, this implies the anodes are consumed as the time goes by ...

The results of electrolysis are the deposition of molten aluminum on the bottom of the cell and the evolution of carbon dioxide on the carbon anode. About 450 grams (1 pound) of carbon are consumed for every kilogram (2.2 pounds) of aluminum produced. About 2 kg of alumina are consumed for each kilogram of aluminum produced. The smelting process is continuous. Additional alumina is added to ...

2019-04-24  Aluminium smelting – energy consumption with and without inert anodes. Aluminium electrolysis is a very energy-intensive process. In 2016, in Norway alone, approx. 18 TWh/year was required to produce 1,282 Mt of aluminium from seven plants (Mosjøen, Sunndal, Høyanger, Årdal, Husnes, Karmøy and Lista). Such electricity consumption is equivalent to 14 per cent of all hydropower generation ...
