Bauxite is actually a general term for the ores which can be used in instry and are mainly composed of gibbsite and gibbsite. Bauxite is the best raw material for the proction of aluminum, and it is also the most important application field. Its consumption accounts for more than 90% of the total output of bauxite in the world
bauxite is the best raw material and the most important application field for the proction of metallic aluminum, which accounts for more than 90% of the total bauxite proction in the world. Although bauxite accounts for a small proportion of non-metal consumption, it is widely used. Mohs hardness is 2.5-3.5
extended data
bauxite ore has various uses:
1. Aluminum smelting instry. Used in national defense, aviation, automobile, electrical appliances, chemical instry, daily necessities, etc
2. Precision casting. Bauxite clinker is processed into fine powder and made into mould for investment casting. For military, aerospace, communications, instrumentation, machinery and medical equipment departments
3. Used for refractory procts. The refractoriness of high bauxite clinker is as high as 1780 ℃, with strong chemical stability and good physical properties
4. Aluminosilicate refractory fiber. It has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conctivity, small heat capacity and mechanical vibration resistance. It is used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical instry, aerospace, atomic energy, national defense and other instries
The high aluminum clinker is put into a high temperature electric arc furnace with melting temperature of about 2000-2200 ℃. After high temperature melting, high pressure and high speed air or steam injection and cooling, the pure white "cotton" - aluminum silicate refractory fiber is formed. It can be pressed into fiber blanket, board or woven cloth to replace refractory bricks for lining of high temperature furnaces in smelting, chemical and glass instries. Firemen can use fire-resistant fiber cloth to make clothes
