The main ingredient of bauxite also known as alumina is aluminum oxide. It is an earthy mineral colored white or gray white and could also appear to be brown yellow or light red due to iron inside it . Calcined Bauxite is produced by high temperature calcination. Product usage Aluminum Industry. Used for national defense, aviation, automotive, electric appliance, chemical industry, daily necessities, etc Precision Casting.Calcined bauxite powder can be used for produce mold precision casting and used for military industry, aviation, communication, instrument, machinery and medical equipment department. Used for Refractory Product .The refractoriness of calcined bauxite could be as high as 1780 .And it also has excellent chemical stability and good physical properties. Silicate Aluminum Refractory Fiber. With advantages such as light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical shock resistance .It can be used for steel, non ferrous metallurgy, electronics, petroleum,
Bauxite is primarily a metallic mineral though it is also used as an industrial mineral. It is the only ore used for large scale aluminium production.Much of the bauxite is formed by the desilication of clays. The alumina-rich components of igneous rocks weather to clay more easily than the mica and chlorite of the phyllites. Bauxite is a product of weathering. The name bauxite is derived from its first study area. It has been classified into laterite and terrarossa types. The laterite type bauxite is formed in situ from crystalline rocks and is rich in gibbsite. The terrarossa type bauxite overlies limestone of dolomite and is rich in bochmite. How do you identify bauxite Bauxite, on the Mohs scale, is usually a mild mineral with a hardness of just 1 to 3. With a pisolitic shape, earthy lustre and a low specific gravity of between 2.0 and 2.5, it is white to grey to reddish brown.
Bauxite is a rock that is most frequently found in tropical or subtropical areas and created from the reddish clay element called laterite soil. Alumina, silica, iron oxides, and titanium dioxide make up majority of the ingredients in bauxite. Chemical Specification: Aluminum Oxide (Al2O3 ) 51.1 % 50.0 % min.
