Bauxite - AccessScience from McGraw-Hill Education

Bauxite is the primary raw ore material used to produce aluminum metal and alumina (Al 2 O 3). It is a naturally occurring weathering product composed of one or more aluminum hydroxide minerals, such as gibbsite [Al(OH) 3], boehmite [AlO(OH)], and diaspore [AlO(OH)].The major impurities in the bauxite ore are clay minerals (usually kaolinite), quartz (SiO 2), iron, and titanium oxides.

For lateritic-type bauxites overlying aluminosilicate rocks, the ore is generally inferred to be derived from weathering of the bedrocks (Mutakyahwa et al., 2003, Hou et al., 2017) i.e. of autochthonous origin.However, for karstic (especially paleo-karstic) bauxite deposits, which are underlain by carbonate rocks, controversies generally exist between autochthonous and allochthonous origins.
