Description of Bauxite
Bauxite main component is alumina, which is a hydrated alumina containing impurities and is a kind of earthy mineral. White or off-white, brown or light red due to iron. Density 3.45g/cm3, hardness 1-3, opaque, crisp. Extremely hard to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. It is mainly used for aluminum smelting and refractories.
