The Lingshou Yijia Mining Co., Ltd. specializing in the production of fluorite. Fluorite (Fluorite), also known as fluorspar, a mineral whose main component is calcium fluoride (CaF2), containing impurities, the substitution of Ca is often Y, Ce and other rare earth elements, in addition to containing a small amount of Fe2O3 SiO2, and trace amounts of Cl, of O3, He et. Fluorite is often significant in nature bright colors, the hardness is lower than the knife. It can be used for preparation of hydrogen fluoride: of CaF2 + of H2SO4 of CaSO4 + 2HF ↑; before artificial fluorite technology is not yet mature, it is one of the manufacture of lenses used in optical glass materials. 
 First, the origin of the name 
 Fluorite are so called because it will fluoresce under ultraviolet or cathode-ray irradiation, but when the fluorite contains some rare earth elements, it will be phosphorescent. In other words, after leaving the ultraviolet or cathode-ray irradiation, the fluorite can still continue to light a long period of time. This phosphorescent fluorite production is not the proportion, but in fact the vast majority of glowing pearl are fluorite materials, generally larger fluorite crystal fluorite glowing pearl can find a very large volume. The hardness of fluorite is lower and brittle, in general, need to be taken to avoid the violent collision, while avoiding exposure to chemical substances. 

 Second, fluorite industrial uses 
 Half of the world fluorspar production for the manufacture of hydrofluoric acid, and then develop the manufacture of cryolite for the aluminum industry. Refrigerator coolant (Freon) use fluorite. 
 The fluorite another important use is the production of hydrofluoric acid. Hydrofluoric acid grade fluorspar (fluorite concentrate) with sulfuric acid reaction in the furnace or tank arising out of the points of anhydrous hydrofluoric acid and water, hydrofluoric acid is a colorless liquid volatile, strong pungent odor and strong corrosion. It is a key raw material for production of various organic and inorganic fluoride and fluorine. In the aluminum industry, the hydrofluoric acid used to produce aluminum fluoride, cryolite, sodium fluoride and magnesium fluoride. In the aerospace industry, hydrofluoric acid is mainly used to produce a jet of liquid propellant missile jet fuel propellant. In the atomic energy industry, hydrofluoric acid is mainly used to produce UF4, generated by the fluorination of UF6, separation by gaseous diffusion or gas centrifuge method 235U. Hydrofluoric acid is the basis of organic fluorine chemical raw materials, through the interaction of chloroform and carbon tetrachloride, to produce toxicity, high chemical stability of fluorinated chlorinated hydrocarbons and fluorocarbons for refrigerants, empty aerosol promote agents, solvents, polymers, intermediates and fluorocarbon resins and elastomers. Hydrofluoric acid and carbon tetrachloride, the reaction products of Freon (usually with F). In addition to as a refrigerant, Freon is also widely used to spray the extinguishing agent, fluorine plastic. In medicine, fluorine organic compounds can also manufacture fluorine-containing anti-cancer drugs, fluorinated cortisone-containing fluorocarbon artificial blood. Inorganic fluoride industry, the production of pesticides, preservatives, protectants and additives, flux and antioxidants. The chemical industry high quality product on fluorite, general requirements for the CaF2 content in 93% to 98% silica and calcium carbonate is harmful impurities, and to strictly limit. Of firefly (fluorine) Stone concentrate quality requirements according to the People's Republic of China GB5690-85 "fluorine stone concentrate." 
 Third, the building materials industry 
 Fluorite is also widely used in glass, ceramics, cement and other building materials industry, and its usage in China accounted for two. In the glass industry, fluorite as a flux, sunscreen added, it can promote the melting of the glass material. Different glass, fluorite amount. Ordinary glass plate, fluorite amount of 1% of the charge; and the amount of alkaline glass ball, fluorite 1% to 2%; oxide glass, fluorite amount compared to 3%; white, cream, stained glass the production process, fluorite, except as a cosolvent, but also for sunscreen, adding amount of 10% to 20% of the charge. The quality of the glass industry fluorite require more stringent requirements of CaF2> 80%; Fe2O3 <0.2%. In cement production, fluorspar as a mineralizing agent to join. Fluorite can reduce the sintering temperature of the charge, reducing fuel consumption, while the enhanced sintering clinker liquid viscosity, and promote the formation of tricalcium silicate. In cement production, the the fluorite amount in the general case for the 4% to 5% to 0.8% to 1%. Cement industry to strict of fluorite quality requirements, general CaF2 content in more than 40 percent can not make specific provision on the impurity content requirements. In the ceramic industry, fluorite is mainly used for the enamel, it can play to help color in the enamel production process and the role of flux. Join the fluorite in red enamel, bright color, bright enamel of ceramic production in the fluorite amount is generally about 10% to 20%. Fluorite is also used in the ceramic industry and cast stone production, the amount of 3% to 10% and 3% respectively. In the building materials industry, due to the different uses, fluorite is not the same quality requirements. At present, China fluorite quality requirements for the building materials industry in the PRC national standard GB19321-88 "fluorite ore powder makes provision.
