  • Bauxite  The Aluminum Association</h3>(*)<p>Bauxite 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 stripmining operations. Bauxite reserves are most plentiful in Africa, Oceania and South America. Reserves are projected to last for ce

  • Bauxite  </h3>(*)<p>Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. Bauxite consists mostly of the aluminium minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase and ilmenite. In 1821 the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France.

  • Bauxite The principal ore of aluminum.  Geology</h3>(*)<p>Many people are surprised to learn that bauxite is not a mineral. It is a rock composed mainly of aluminumbearing minerals. It forms when laterite soils are severely leached of silica and other soluble materials in a wet tropical or subtropical climate.
