Fluorite application field and prospects

Fluorite fluorite recognize human applications it is possible to reduce the melting point of the nature of refractory mineral starting. In traditional industries, fluorite in metallurgical industry for the refining of iron, steel and iron alloys in a flux, slagging agents; feedstock production of artificial cryolite, cryolite flux in the electrolytic production of aluminum do, treated with hydrofluoric acid Synthesis of aluminum fluoride, sodium fluoride, etc.; enamel brightener, glass opacifier and the like. Fluorite is used as a mineralizer for the production of cement clinker, which makes the cement raw material easy to calcine, lowers the sintering temperature, shortens the firing time and saves energy. When fluorite is used to produce raw materials for emulsified glass, opaque glass, and colored glass, the temperature at the time of glass smelting can be lowered, the melt can be improved, and the melting can be accelerated, thereby reducing the fuel consumption ratio. Fluorite is used to make fluxes and opacifiers for ceramic and enamel processes. The optical industry uses fluorite to produce an optical objective without a spherical image, a spectrometer prism, a window material that radiates ultraviolet rays and infrared rays, and a colorless transparent large fluorite crystal as a process fluorite.

At present, fluorite is used in emerging industries such as high-performance materials, medicine, pesticides, refrigeration, and national defense. In the United States and some European countries, fluorite has been used as a strategic mineral to limit its mining and development, such as: Stone is a strategic reserve resource to stop mining. Hydrofluoric acid made of fluorite, for the production of jets of liquid propellant missile jet fuel propellant for the aerospace industry, with hydrofluoric acid purification nuclear fuel for the nuclear energy industry, hydrofluoric acid used in petrochemical, Semiconductor manufacturing, metal processing, non-metal purification and glass processing. In the organic fluorine chemical industry, hydrofluoric acid is mainly used to produce fluorine-containing alkanes, fluorine-containing alkanes (such as HFC-134a) are used in industrial and civil refrigeration systems, and fluorine-containing alkanes are also the main raw materials for fluoropolymers. Production of super environmentally friendly cleaning agents. Fluoropolymers (such as fluoroplastics, fluoroelastomers and fluorine coatings) have high thermal stability, high chemical inertness, strong electrical insulation and low friction coefficient. They are widely used in automobiles, ships, airplanes, chemicals, agriculture, fireproof textiles. And medical equipment, etc. Fluorine chemical products are the basic materials necessary for high-tech industries. Fluorine chemical industry is a basic industry with leading and strategic status. Hydrofluoric acid is one of the key basic raw materials for fluorine chemical industry. Fluorite is the most suitable for producing hydrofluoric acid. The economy, the most critical mineral raw material, whether the supply of fluorite is long enough is related to the sustainable development of the world's industry. China has realized the strategic position of fluorite. The State Council has introduced measures to limit the production of refractory clay fluorite, regulate refractory clay fluorite and limit the export of fluorite.
