Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .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%to88%.the heating is carried out in rotary kilns.Specification :

1. Aluminium metallurgy.
2. Precision casting / Investment casting: Bauxite grog fines can be made into mold for precision casting.
3. Refractory: refractoriness of high quality bauxite can reach 1780°C with good chemical stability and mechanical performance.
4. Aluminium silicate refractory fiber: high quality bauxite can melt in electric arc furnace, producing aluminium silicate refractory fiber, which can be made into ceramic fiber blanket, plate,cloth etc.
5. Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining.
6. Producing bauxite cement.
7. Abrasives grade bauxite.
8. Ceramics industry.
9. Chemistry industry for all kinds of aluminium compound.Product Pictures:Pacakge:
