Uses of Bauxite Definition, Different Applications & Formula

What is Bauxite? Bauxite is primarily a metallic mineral though it is also used as an industrial mineral. It is the only ore used for large scale aluminium production. Although aluminium is the most abundant metallic element in the earth’s crust constituting about 8%, it usually occurs in clays, soil and rocks that cannot be utilized for its extraction.

Extraction of Aluminium Hall-Heroults Process & Uses

The Hall-Heroult process is widely used in the extraction of aluminium. In Hall-Heroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering of the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with the lining of carbon and graphite rods is used.
