    Oct 21, 2020  “Bauxite is primarily a metallic mineral though it is also used as an industrial mineral. It is the only ore used for large scale aluminium production.” Much of the bauxite is formed by the desilication of clays. The alumina-rich components of igneous rocks weather to clay more easily than the mica and chlorite of the phyllites.
