High Alumina Bauxite also called bauxite aggregate,its composition is very complex,and the general term of Hydrous Alumina Ore with different geological origin. Such as boehmite, diaspore and gibbsite (Al2O3 - 3H2O); some are diaspore and kaolinite (2SiO2 Al2O3 2H2O) Company; some kaolinite, and with the increase of the content of kaolinite, which is generally the bauxite or kaolinite clay. Bauxite is usually formed by chemical weathering or exogenic action. There are few pure minerals and always contain some foreign minerals, which contain more or less clay minerals, iron minerals, titanium minerals and detrital heavy minerals.

Calcined Bauxite Application:
1. Aluminium metallurgy
2. Precision casting / Investment casting:
bauxite grog fines can be made into mold for precision casting.
3. Refractory: high alumina bauxite's refractoriness can reach 1780°C.
It is charactered by good chemical stability and mechanical performance. (Al2O3 ≥48% with low Fe2O3)
4. Ceramics industry
5. Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under 2000°C-2200°C in the electric arc furnace.After a series of processing, it can become aluminium silicate refractory fiber,
which can be made into fiber blanket, plate,cloth.
6. Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining
performance.
7. Producing bauxite cement
8. Abrasive
9. Chemistry industry for all kinds of aluminium compound.
