SEPPE Calcined Bauxite

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...
