Bauxite is a mixture of minerals that contain various concentrations of hydrated aluminum oxides, as well as impurities. The primary ore minerals are gibbsite (alumina tri-hydrate), boehmite and diaspore (alumina monohydrates).
Gibbsite-rich bauxite is preferred as it can be refined at lower digestion temperatures than the other types of alumina bearing minerals.
Bauxite is usually reddish-brown, but can also be white, tan, and yellow, depending on the type and concentration of iron minerals present. It also has a wide range of textures, but is typically dull to earthy in luster and can look like clay or soil.
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. 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.
5. Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining
6. Producing bauxite cement
8. Ceramics industry
9. Chemistry industry for all kinds of aluminium compound.
