Bauxite Technical Note What is bauxite? Hence, the major deposits are generally close to the surface. Bauxite is a mixture of aluminium minerals, clay minerals, and insoluble materials. Three aluminium minerals can occur in bauxite: gibbsite, boehmite and diaspore. Bauxite is the world's principal source of aluminium and can vary

It can be further calcined to Al 2 O 3, alumina, in a rotary kiln at 800 defrees F. From the kiln, the alumina is allowed to cool and it is stored for shipment to the aluminum plant. To produce aluminum, the alumina is reduced in a electrical reduction cell which produces pure Al plus carbon dioxide (CO 2 ).
