How Is Bauxite Formed? - Reference

2020-3-25  Bauxite ore is formed when the surrounding soil or rock is dissolved by natural weathering processes until it forms a new type of rock that is usually rich in aluminum ore. Though both types are used for aluminum production, the most valuable type of bauxite ore is lateritic ore. The type of bauxite ore produced is heavily dependant on the ...

Bauxite - an overview ScienceDirect Topics

Lateritic weathering and bauxite formation are generally favored by largely humid, tropical and subtropical climates. Bauxites are industrially important for both Al metal supply and non-metallurgical use and they represent the only raw material used in the production of alumina on a commercial scale. Gallium is a common by-product of Al ...

2021-11-18  Composition. Bauxite consists predominantly of minerals such as gibbsite (Al(OH) 3), boehmite (AlO(OH)), and diaspore (AlO(OH)), as well as lesser amounts of clays (such as kaolinite), silt, and iron oxides and hydroxides. It may also contain small amounts of anatase (TiO 2).. Formation. Bauxite is a laterite, formed by the intense weathering of surface rocks.

Bauxite deposits invariably contain a range of impurities, ranging from organic material to trace elements such as Ga, Zn, Pb, P and Be. Table 2.1 shows typical compositions of a range of smelter aluminas. In the Bayer process, many impurities are at least partially soluble in the caustic digestion liquor and may be carried over into precipitation if they are not removed in the
