Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts.
To achieve this, the ore is crushed and roasted to convert sulfides into oxides and finally smelted to produce matte. It is then subjected to various refining processes, with the final step being the electrolysis. For example, bauxite has to be processed into pure aluminum oxide before it can be then converted into aluminum by electrolysis.
