Bauxite also calle bauxite aggregate,its composition is very complex,and the general term of Hydrous Alumina Ore with different geological origin. Such as boehmite, diaspore and gibbsite (Al2O3 - 3H2O); some are diaspore and kaolinite (2SiO2 Al2O3 2H2O) Company; some kaolinite, and with the increase of the content of kaolinite, which is generally the bauxite or kaolinite clay. Bauxite is usually formed by chemical weathering or exogenic action. There are few pure minerals and always contain some foreign minerals, which contain more or less clay minerals, iron minerals, titanium minerals and detrital heavy minerals.
