BAUXITE
Introduce
Bauxite actually refers to the industrial use of bauxite, bauxite as the main mineral composed of ore. Bauxite is the best raw material for the production of metal aluminum, and it is also the most important application field, accounting for more than 90% of the total output of bauxite in the world. Although the proportion of bauxite in the amount of non-metal is small, its use is very wide. Mohs hardness 2.5-3.5.

Application
Bauxite ore has various uses:
(1) Aluminum smelting industry: Used in national defense, aviation, automobile, electrical appliances, chemical, daily necessities, etc.
(2) Precision casting: The bauxite clinker is processed into fine powder and then cast. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment departments.
(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. Used in iron and steel, non-ferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense and other industries. It is the high aluminum clinker into the melting temperature of about 2000 ~ 2200ºC of high temperature electric arc furnace, high temperature melting, high pressure high speed air or steam injection, cooling, the formation of aluminum silicate refractory fiber. It can be pressed into fiber blanket, board or woven cloth instead of smelting, chemical, glass and other industrial high temperature kiln lining refractory brick. Firemen can make clothes out of fire-resistant cloth.
(5) With magnesiac and bauxite clinker as raw materials, adding appropriate binder, used for pouring full steel barrel lining effect is very good.
(6) Manufacturing bauxite cement, grinding materials, ceramic industry and chemical industry can make aluminum of various compounds.
Among THE MOST IMPORTANT uses are: refining metal aluminum in the aluminum industry, as refractory and abrasive materials, and as raw materials for high-aluminum cement. Different uses of ore, its quality requirements vary. Industry standard for bauxite ore (YS/T78-94) issued by China Nonferrous Metals Industry Corporation in 1994. According to this standard, bauxite can be divided into three types: sedimentary type diaspore, accumulation type diaspore and laterite type diaspore. In addition to the provisions on the chemical composition of bauxite, the standard also requires that the moisture of sedimentary type diaspore shall not exceed 7%, and that of accumulation type diaspore and laterite type diaspore shall not exceed 8%. In addition, the particle size of bauxite ore shall not be greater than 150mm. Bauxite ore shall not be mixed with soil, limestone and other sundry.
The non-metallic uses of bauxite are mainly as refractorials, grinding materials, chemicals and raw materials for high-aluminum cement. Although the proportion of bauxite in the amount of non-metal is small, its use is very wide. For example, in terms of chemical products, sulfate, trihydrate and aluminum chloride can be used in papermaking, water purification, ceramics and petroleum refining. Activated alumina can be used as catalyst, catalyst carrier and physical adsorbents such as decolorization, dehydration, degassing, deacidification and drying in chemical, oil refining and pharmaceutical industries. Aluminum chloride produced by r-Al2O3 can be used for organic synthesis applications such as dyes, rubber, medicine and petroleum. 3% ~ 5%Al2O3 in glass composition can improve melting point, viscosity, strength; Grinding material is the main raw material of advanced grinding wheel and polishing powder; Refractory is an indispensable furnace-building material in the industrial sector.
