Bauxite Applications

Bauxite Applications

Bauxite using a lot to producing aluminum. Bauxite also uses in extraction of gallium Bauxite is the main source of the rare element gallium. During the process of extracting alumina from bauxite in the Bayer process, gallium accumulates in the molten sodium hydroxide. Due to its low hardness, Bauxite is used as a suitable pulp lubricant in steel making and is a suitable and cheaper alternative to fluorine. By “sintering” bauxite, a suitable abrasive material for sand blasting processes can be obtained. Bauxite is produced by crushing and pulverizing bauxite and agglomerating it at high temperature. These agglomerates are used to reduce wear in sand blast parts. Refractory cement is obtained by mixing lime with an equal proportion of bauxite. Alumina and silica form mullite, which increases the melting point.
