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.

Although bauxite is commonly known as a mineral, it is an ore composed of minerals. Properties of Bauxite Bauxite, which consists of aluminum oxide and minerals such as boehmite, gibbsite, corundum and diasporite, is in the form of a heterogeneous mixture and in amorphous structure.

Calcined bauxite (aluminium oxide) is produced from Refractory Agglomerated Super Calcined (RASC) bauxite. The main constituent is the mineral corundum. Calcined bauxite can be characterised by: High Mohs hardness of 8.5; High inertness in various media. Basic properties

About Bauxite (Aluminium) Hide Bauxite is the main ore of aluminium (aluminum). It is composed primarily of impure aluminium hydroxides along with a lot of silica, iron and other impurities. It is usually formed as a weathering product of rocks rich in aluminium silicates. Aluminium (or Aluminum) is a silvery soft nonmagnetic metal.

The bauxite ore, with the scientific name of alumyte and bauxite and extremely complex composition, is a general term for various alumina ores containing water from very different geological sources. Bauxite ores are usually formed by chemical weathering or exogenous action, and few of them are pure minerals, and they always contain some impure ...
