Bauxite is the ore from which aluminium is made. Jamaica contains some of the largest known deposits of bauxite in the world. The mining areas are located in the western and central parts of the island. After mining, most of the bauxite is carried to alumina plants where it is refined into alumina. The alumina (or in some cases unrefined ...

In Steel Industry. In the steel, industry, bauxite is used to control desulphurising power and fluidity of the slag and provide material for blast furnaces of the cement during iron making. It is also used in oxygen furnaces as an additive to control the viscosity of the slag. Here bauxite is used as a source of alumina to control viscosity.
