Bauxite The Aluminum Association

ResourcesEnvironmentFutureDiscoveryBauxite ore is the worlds primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions. The ore is acquired through environmentally responsible strip-mining operations. Bauxite reserves are most plentiful in Africa, Oceania and South America. Reserves are projected to last for ce

Production process - EUROPEAN ALUMINIUM

Aluminium production begins with bauxite, the “aluminium ore”. Most bauxite is mined in tropical areas, with around 50km 2 of new land mined each year. At the same time, a matching area of land is restored to nature. Alumina production Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic ...

Aluminium smelting - Wikipedia

Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process.Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.. This is an electrolytic process, so an aluminium smelter uses huge amounts of electricity; smelters tend to be located close to large power stations, often hydro-electric ones ...
