Aluminum

a) Native alumina is found as the mineral corundum. Most bauxite is refined by the Bayer process to remove impurities and produce a nominal 99.5% Al2O3 product.

b) Four types of alumina are generally utilized: calcined, tabular, hydrated, and synthetic boehmite. Aluminas are a family of aluminum oxides (Al2O3) that can take many forms.

c) As a general term, “alumina” refers to the lower temperature transition alumina forms.

• Alumina (Al2O3) Formula: Al2O3

Chemical Properties

Specifications

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).

Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. As of 2010, approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis.[9] Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory. We can supply Bauxite from Indian in bulk vessel and containers.
