Varieties Some minerals associated with bauxite are gibbsite, boehmite and diaspore. Mineral Group Hydroxides and oxides because of the different physical properties. Environment Deposits of bauxite are mainly formed from rocks that contain aluminum. In some locations bauxite may or may not be originally from the site where it is found.
A soft, aluminum-containing ore. Bauxite is an impure mineral that contains hydrous aluminum oxides and aluminum hydroxides. In 1821, the first commercial source of bauxite was a mine near Les Baux, France since then deposits have been found worldwide.

An ore is a rock that contains minerals with useful elements. Aluminum in bauxite ore Figure below is extracted from the ground and refined to be used in aluminum foil and many other products. The cost of creating a product from a mineral depends on how abundant the mineral is and how much the extraction and refining processes cost.
Aluminum is a metallic element with the symbol Al.For more information about its atomic structure, weight and more, see our Periodic Chart of the elements. The primary ore of aluminum is bauxite Note Bauxite specimens are available on our minerals page.It is plentiful and occurs mainly in tropical and sub-tropical areas such as Africa, the West Indies, South American and Australia.
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 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.
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
