The industrial extraction of aluminum from bauxite is performed using the Bayer process. Calcined bauxite is produced by calcination of bauxite ore at 900 to 1700 °C by a rotary kiln or multiple hearth furnace kiln ( known as a vertical calciner). Applying temperatures about 1650 to 1700 °C leads to the sintering or frittage.
CALCINED BAUXITE alcined bauxite is an important raw material for two main markets: refractories and abrasives. Smaller volumes are consumed in other appliions including proppants, welding fluxes, and antiskid surfaces. While the process of calcining bauxite for each of these appliions is fundamentally the same (ie. it involves
The calcination process is carried out at different temperatures starting from 850 °C to 1600 °C depending upon the need of our valuable clients. Ravani Ceramics produces Calcined Bauxite for various appliions such as refractory bricks, abrasives, steel polishing, etc.
