The Physical properties of minerals are used by Mineralogists to help determine the identity of a specimen. Some of the tests can be performed easily in the field, while others require laboratory equipment. For the beginning student of geology, there are a number of simple tests that can be used with a good degree of accuracy.

Bauxite, an aluminum ore, is the world's main source of aluminum. It consists mostly of the minerals gibbsite Al (OH)3, boehmite γ-AlO (OH) and diaspora α-AlO (OH), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase TiO2, Ilmenite, FeTiO3, and FeO TiO2. Physical Properties of Bauxite.
Principle Uses of Bauxite. The principle use of Bauxite is the extraction of aluminium minerals as a metal. Aluminium has been extensively used commercially as well as in day-to-day human life in the form of cooking utensils, construction of doors and windows, furniture, cosmetics, paints and varnishes, aluminium hydroxide medicines, etc.
Conditions within the digester (caustic concentration, temperature and pressure) are set according to the properties of the bauxite ore. Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C.
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.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 (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral …
Bauxite Mineral. Bauxite is a mixture of minerals which contain, as well as impurities, different concentrations of hydrated aluminium oxides. Gibbsite (alumina trihydrate), boehmite, and diaspore (alumina monohydrates) are the main ore minerals. Bauxite is a high-aluminum-content rock. That is the main ore that aluminium is mined from.

Bauxite, once considered as a hydrated aluminum oxide mineral, is actually a mixture of minerals, which technically makes it a rock. It consists mostly of the minerals gibbsite Al(OH) 3, boehmite AlO(OH), and diaspore AlO(OH), together with the two iron oxides goethite and hematite, as well as the clay mineral kaolinite.
Bauxite is a mineral with a dull, earthy luster which is usually white or gray, though sometimes can be found stained by yellow, orange, red, pink, or brown by iron or included iron minerals. It has no cleavage, a low specific gravity, and the Mohs Hardness Scale score is between 1 and 3. Its streak is usually white, but its iron stain can discolor.
Low-grade bauxite was added to magnesium phosphate cement as the mineral admixture. • The use of LG-bauxite in MPC can improve the properties of the fresh mixture. • The mortar blended with 10% LG-bauxite showed the best mechanical properties. • The new formed hydrates were detected and the microstructures were analyzed.
The Mineral gibbsite. Gibbsite is one of the three component minerals of the economically important aluminum ore Bauxite. Gibbsite was first discovered in 1820 by Chester Dewey (1784-1867) of Williams College, Massachusetts. It was first thought to be Wavellite, but a year later it was determined to be a separate mineral species and was ...
