Product Description
Description of bauxite:
Bauxite (aluminous soil; bauxite), also known as alumina or bauxite, the main component is alumina, hydrated alumina system containing impurities is an earthy mineral. White or gray, because iron and brownish yellow or pink. Density 3.45g / cm3, hardness 1-3, opaque, brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminum smelting, manufacture refractories.
Application of bauxite:
1. Aluminium metallurgy
2. Precision casting / Investment casting:
3. Refractory: high alumina bauxite’s refractoriness can reach 1780°C.
4. Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.
5. Producing bauxite cement
6. Chemistry industry for all kinds of aluminium compound.
7. Abrasives
8. Ceramics industry.
