bauxite rich in aluminium

Bauxite (Aluminium): Mineral information, data and localities.

Bauxite is the main ore of aluminium (aluminum). It is composed primarily of impure aluminium hydroxides along with a lot of silica, iron and other impurities. It is usually formed as a weathering product of rocks rich in aluminium silicates. Aluminium (or Aluminum) is a silvery soft nonmagnetic metal. It is the most widely-used metal after ...
