SEPPE Calcined Bauxite


Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite is obtained by calcining (heating) superior grade bauxite at high temperature (from 850℃ to 1600℃). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57% to 58% in raw bauxite, calcined bauxite has an alumina content of 84% to 88%.


The calcined bauxite can be processed into bauxite sand and bauxite powder of different particle sizes, both of which can be directly used as refractory sand. It has a very high status in the field of refractory materials. 


Calcined bauxite size is available from 0-1, 1-3, 3-5mm; also 100mesh, 200mesh, 325mesh...
