Aluminum Ore
Bauxite is an aluminium ore and is recognised as one of the main sources of aluminium. It typically contains different minerals such as boehmite (γ-AlO (OH)), gibbsite (Al (OH) 3) and diaspore (α-AlO (OH)) mixed with the kaolinite, goethite, hematite, and minor amounts of anatase (TiO 2) and ilmenite (FeTiO 3 or FeO.TiO 2) ( Liu et al., 2011 ).
