Bauxite is a naturally occurring heterogeneous material composed primarily of aluminum hydroxide minerals with relatively small and variable amounts of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. This paper reports that the major uses for bauxite, beyond aluminum metal production, are in refractories, abrasives, chemicals, aluminous cements, and specialty products such as proppants for use within the petroleum industry. Bauxites for these select markets must meet more rigid compositional requirements with respect to iron oxide, silica, and titania contents than those used for the production of aluminum. In addition, refractory and abrasive grades of bauxite are calcined before being marketed for use by it.
