Bauxite - an overview ScienceDirect Topics

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 ...

2021-9-28  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. Bauxite contains typically 40–60% aluminium oxide (alumina) in the form of several hydrous alumina phases (gibbsite, Al (OH)3, boehmite (AlOOH) and diaspore (ALOOH), and with smaller amounts of iron, silicon and titanium compounds as well as other trace impurities. From: Fundamentals of Aluminium Metallurgy, 2011.
