Calcined Bauxite is produced by the sintering/calcining of low-iron, low-alkali containing raw bauxites at temperatures of 1600 – 1800°C. In this calcination process the high refractory mineral phases corundum and mullite are formed. For this reason, calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants. Calcined Bauxite is available run of kiln i.e. uncrushed or in fractions and as ball-milled powder, either in bulk or bagged according to customers’ requirements.
