Bauxite is the ore from which aluminium is derived. Bauxite ore is refined into alumina, a white powder which is the feedstock for aluminium smelters. Smelting produces liquid aluminium, which is cast into the wide range of primary aluminium products which we supply to our customers, semifabriors that are part of the supply chains of end user industries from aerospace to construction.
TENORM: Bauxite and Alumina Production Wastes | US EPA
· The Bayer Process. The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.
Bauxite
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γAlO(OH)) and diaspore (αAlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH) 4) and small ...
