Audited Supplier Bauxite is a natural, very hard mineral and is primarily comprised of aluminaum oxide compounds (alumina), silica, iron oxides and titanuim dioxide, approximately 70 percent of the world's bauxite production is refined through the bayer chemical process into alumina.
Calcined Bauxite is produced by sintering high-alumina bauxite in rotary, round or shaft kilns at high temperatures. This process of calcining (heating) bauxite in kilns removes moisture and gives Calcined Bauxite its high alumina content and refractoriness, low iron, and grain hardness and toughness. Its thermal stability, high mechanical strength and resistance to molten slags make Calcined Bauxite an ideal raw material in the production of many refractory, abrasive and specialty product applications.
Applications
(1) Aluminum smelting industry.
(2) Precision casting. Bauxite clinker is processed into fine powder and then cast.
(3) For refractory products. High bauxite clinker refractoriness up to 1780ºC, strong chemical stability, good physical properties.
4) Aluminum silicate refractory fiber. It has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical vibration resistance.
(5) Using magnesia and bauxite clinker as raw materials and adding appropriate binder, it can be used for casting steel barrel lining.
(6) Manufacturing bauxite cement, grinding materials, ceramic industry and chemical industry can be made of aluminum compounds.
Bauxite can be divided into three categories: bauxite raw material, light-burned bauxite, and bauxite clinker. Depending on its grain size, it is categorized as aggregate or powder. The main component is alumina, which is hydrated alumina containing impurities and is an earthy mineral. White or off-white, brownish-yellow or light red due to iron content. The Density of the bauxite is around 3.9-4g/cm3, its hardness is about 1-3, opaque and brittle. It is extremely hard to melt and insoluble in water, but soluble in sulfuric acid and sodium hydroxide solution.
Cooked bauxite is smelted from raw bauxite by high temperature heating in rotary kiln, shaft kiln or inverted flame kiln.
