Bauxite mining in Australia Wikipedia
Uses. Bauxite is a raw material used primarily in the production of bauxite ore is refined into alumina before being smelted into aluminium. Australia is known for its highgrade ore, especially in the Weipa and Gove deposits. The quality of bauxite ore is determined by its available alumina (Al 2 O 3) presence of impurities, which make the ore more difficult to ...

Bauxite Mining Encyclopedia of Arkansas
Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments. Soils formed under these conditions are termed laterites. In Arkansas, the aluminumenriched soils are the result of the decomposition and lateritic weathering of nepheline syenite, an intrusive igneous rock.

Bayer process Wikipedia
Bayer process. The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 3060% aluminium oxide (Al 2 O 3 ), the rest being a mixture of silica, various iron oxides, and titanium dioxide. [1]
