Introduction of calcined bauxite :

Raw Bauxite is the primary source of aluminium metal.The Clinker are pale yellow and dark gray, it is mainly used for high aluminum refractory material, can also be used to make the fused corundum, bauxite cement, abrasives, aluminium compound, precision casting. 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 75%to 90%, the heating is carried out in rotary kilns

Applications of calcined bauxite :

1. Aluminum industry.

2.  Precision casting.

3.  Refractory industry.

4. Silica acid aluminum firefibre

5. Mixed with magnesium oxide,it can be an nice bonding agent,especially for pouring entire steel teeming ladle lining

6.  Manufacture bauxite cement,grinding abrasives.

7. Ceramic industry,and chemical industry for making aluminium compounds
