The main component of bauxite is alumina, which is the main raw material for aluminum refining and refractory materials. White or gray-white, brownish yellow or light red due to the iron content. Density 3.45g/cm3, hardness 1 ~ 3, opaque, brittle. Extremely difficult to melt, insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Regional distribution China bauxite resources are relatively rich in 18 provinces, autonomous regions and municipalities directly under the Central Government has identified 205 bauxite production sites, of which 72 large-scale production sites (excluding Taiwan), mainly in Shanxi, Shandong, Hebei, Henan, Guizhou, Sichuan, Guangxi, Liaoning, Hunan and other places. Investment Prospects 1. It can be used in the aluminum industry. Used in national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities, etc. 2. It can be used in precision casting. Alumina clinker is processed into fine powder and made into casting molds for precision casting. Used in military, aerospace, communications, instrumentation, machinery and medical equipment. 3. Can be used for refractory products. High alumina bauxite clinker refractoriness up to 1780 ℃, chemical stability, good physical properties. 4. Aluminosilicate refractory fiber. Used in iron and steel, non-ferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense and other industries, firefighters can use refractory fiber cloth made of clothes. 5. Manufacture of bauxite cement, abrasive materials, ceramic industry and the chemical industry can make a variety of aluminum compounds. Bauxite Grinding Preparation Bauxite powder is a fine powder made from calcined cooked bauxite ore processed by Raymond mill, the particle size is usually 100 mesh-325 mesh, which is widely used in the refractory industry. Usually the process is first crushed by jaw crusher, and then screened into the bauxite Raymond mill or bauxite ultrafine mill for bauxite powder preparation, so as to make it more widely used.
