Bauxite Rich In Aluminium

  • Bauxite (Aluminium): Mineral information, data and

    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.

    2021-6-27  Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium. The principal minerals in bauxite are gibbsite (Al 2 O 3.3H 2 O), boehmite (Al 2 O 3.H 2 O) and diaspore, which has the same composition as boehmite, but is denser and harder. Australia is the world's largest producer of bauxite, representing 28% of global production in 2012.
