Aluminium Ore

In its mineral form Bauxite, Aluminium is the most abundant metal in the earth's crust. Bauxite contains one of a variety of hydrated aluminium oxides (gibbsite, boehmite or diaspore), which are often expressed as Al2O3xH2O but are more commonly regarded as impure Al2O3. Bauxite is claylike and earthy, and ranges in colour from white to deep brown or red according to the nature and quantity of its components. The major impurities in Bauxite are iron oxides (goethite & hematite), silicon dioxide, the clay mineral kaolinite as well as small amounts of anatase (TiO2). Consequently, its composition varies considerably with alumina constituting from about 50% to about 70%. Aluminium content can be accurately and precisely determined over a broad analytical range simultaneously along with Si, Fe, Mn, Ti, Zr and up to 20+ other elements.
