what is the chemical formula for bauxite
It consists mostly of the minerals gibbsite Al(OH) 3, boehmite Î³-AlO(OH) and diaspore Î±-AlO(OH), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase TiO 2.n 2009, Australia was the top producer of bauxite with almost one-third of the world's production, followed by China, Brazil, India, and Guinea. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.
