Composition Of Alumina In Bauxite Ore

Bauxite Ore Analysis: Aluminum Associated Impurities

In its mineral form Bauxite, Aluminum is the most abundant metal in the earth's crust. Bauxite contains one of a variety of hydrated aluminum oxides (gibbsite, boehmite or diaspore), which are often expressed as Al 2 O 3 xH 2 O but are more commonly regarded as impure Al 2 O 3. Bauxite is claylike and earthy, and ranges in color from white to ...
