Bauxite
Bauxite (aluminous soil; bauxite) is also called bauxite or bauxite. Its main component is alumina, which is hydrated alumina containing impurities. It is an earthy mineral. White or off-white, brown or light red due to iron content. Density 3.45g/cm3, hardness 1~3, opaque and brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid and sodium hydroxide solutions. Mainly used for smelting aluminum and making refractory materials.

Bauxite ore has many uses:
(1)
Aluminum smelting industry. Used in national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities, etc.
(
2)
Precision casting. Alumina clinker is processed into fine powder and made into casting molds and then precision cast. Used in military, aerospace, communications, instrumentation, machinery and medical equipment sectors.
(3)
Used in refractory products. High alumina clinker has a refractoriness of up to 1780°C, strong chemical stability and 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 resistance to mechanical vibration. Used in steel, non-ferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense and other industries. It puts high-aluminum clinker into a high-temperature electric arc furnace with a melting temperature of about 2000-2200°C. After high-temperature melting, high-pressure and high-speed air or steam injection, and cooling, it becomes white "cotton" - aluminum silicate. Fire resistant fiber. It can be pressed into fiber blankets, boards or woven cloth to replace the refractory bricks lining high-temperature kilns in smelting, chemical, glass and other industries. Firefighters can use fire-resistant fiber cloth to make clothing.
(5)
Using magnesia and bauxite clinker as raw materials, and adding appropriate binding agents, the effect of casting the overall lining of steel drums is very good.
(6)
Manufacture of bauxite cement, abrasive materials, ceramic industry and chemical industry can produce various aluminum compounds.

, strong chemical stability and good physical properties.
Aluminum Smelting Industry
National defense, aviation, automobiles, electrical appliances, chemicals, daily necessities, etc.
Precision Casting
The alumina clinker is processed into subdivided parts and made into molds and then precision cast. Used in military, aerospace, communications, instrumentation, machinery and medical equipment sectors.
Others
Aluminum silicate refractory fiber; using magnesia and bauxite clinker as raw materials, adding appropriate binders, used to pour the integral barrel lining of steel drums; manufacturing bauxite cement, abrasive materials, ceramic industry and chemical industry that can make aluminum. compound.
The non-metallic uses of bauxite are mainly as raw materials for refractory materials, abrasive materials, chemicals and high-alumina cement. Although the proportion of bauxite used in non-metallic applications is small, its uses are very wide.
