What are the uses of bauxite mineral?

Calcined bauxite is bauxite that has been heated to such a high temperature that it converts from bauxite (Mohs 2) to corundum, which is extremely hard (Mohs 9) Calcined bauxite in the form of 1 mm to 2 mm particles is literally glued to areas where skidding is a problem...

BAUXITE ORE

Bauxite, an aluminum ore, is the world's main source of aluminumIt consists mostly of the minerals gibbsite Al(OH)3, boehmite γ-AlO(OH) and diaspora α-AlO(OH), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase TiO2, Ilmenite, FeTiO3, and ,...
