Bauxite is used principally as the raw material in the production of aluminium metal. Nonetheless, beyond this are a number of very significant non-metallurgical applications, mainly abrasives, cements, chemicals, and refractories. Bauxites used in producing end products for these special applications must meet much more stringent compositional and physical requirements than the crude ore commonly employed for aluminium production, and as such, are limited to a few specific sources, such as Guyana, China, and now Brazil. This article reviews the major sources, applications, and requirements of the global nonmetallurgical bauxite industry.
