Bauxite is the principal aluminum ore consisting of a mixture of minerals, namely gibbsite (Al(OH)3), boehmite (γAlO(OH)) and diaspore (αAlO(OH)), and the iron oxides goethite and hematite. It can also contain smaller amounts of the clay mineral kaolinite and traces of anatase (TiO2) and ilmenite (FeTiO3).
Bauxite deposits form the major source of aluminum in our industrial world. The major aluminum phases recognised in bauxites and laterites are gibbsite also known as hydrargillite (γAl(OH)3), boehmite (γAlO(OH)), and diaspore (αAlO(OH)).
Bauxite is an aluminium ore and is the main source of aluminium. This form of rock consists mostly of the minerals gibbsite Al(OH) 3, boehmite γAlO(OH), and diaspore αAlO(OH), in a mixture with the two iron oxides goethite and hematite, the clay mineralkaolinite, and small amounts of anatase TiO 2 .

Bauxite is technically a rock rather than a mineral because it consists of multiple minerals. Those minerals include: diaspore, gibbsite, boehmite, goethite, hematite, and kaolinite AP file
Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γAlO(OH)) and diaspore (αAlO(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 ).
The principal ore of aluminum is bauxite, a complex mixture of a number of aluminum hydroxides and hydrous aluminum oxides. The most common aluminumbearing minerals in bauxite are gibbsite (AlOH3), boehmite (AlO(OH)), and diaspore (AlO(OH)). In .
More than 160 million metric tons of bauxite are mined each year. In terms of physical properties, Bauxite has different composition. What it means is that Bauxite contains a mixture of oxides like aluminum hydroxides, hydrous aluminum oxides, and minerals like gibbsite, boehmite and diaspore including some clay minerals. It also contains ...
Jul 21, 2007· Answers. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the polymorphs boehmite and diaspore. Bauxites are typically classified according to their intended commercial application: abrasive, cement, chemical, metallurgical, refractory, etc.
Bauxite is the world's main source of aluminium. It consists mostly of the minerals gibbsite (Al(OH) 3 ), boehmite (γAlO(OH)) and diaspore (αAlO(OH)), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase (TiO 2 ) and ilmenite (FeTiO 3 or 2 ).
containing boehmite and especially diaspore are more intractable to treatment and are termed hightemperature bauxites. For a bauxite ore to be economically processed it typically contains 3050% of extractable (termed available) alumina, up to 20% of iron oxides and 25% of silica in reactive clays (typically kaolinite).
The bauxite deposits in the Weipa area consist of a 12m layer of pisolitic or peasized bauxite. The ore is banded, including alternating bands of aluminum ore minerals including gibbsite and boehmite, alternating with clayrich and ironoxides including hematite and goethite.
