1.Description:
Bauxite is also called aluminous soil. The main component is alumina, which is a hydrated alumina containing impurities and is a kind of earthy mineral.
2.Characteristics:
Bauxite is generally formed by chemical weathering or exogenous effects.There are few pure minerals,always containing some impurity minerals, and more or less clay minerals,iron minerals, etc.
3.Application:
It is used in aluminum smelting industry,precision casting,for refractory products.
