Bauxite Mining Encyclopedia of Arkansas

2020-9-21  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 aluminum-enriched soils are the result of the decomposition and lateritic weathering of nepheline syenite, an intrusive igneous rock. During the

Bauxite Mining The Australian Aluminium Council

The first step in producing aluminium is mining this ore. Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the Caribbean, South America and Australia. Australia is the largest producer of bauxite, with five large mines supplying around 30 per cent of global production.

Mining and Refining Process

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which

Surface mining is more common than underground mining because most of the bauxite deposits occur near the surface. The extraction of bauxite takes place by shallow, open-cut mining following the open-pit method. The bauxite ores content is of different types and the most amount of clay, and need to be washed before the process (Donoghue et al., 2014; Lee et al., 2017).
