Question 1: What can fluorite do? Fluorite, also known as fluorite, is also called Wuhua stone. Its chemical composition is calcium fluoride, which is a common mineral in nature and contains fluorine. The highest industrially important mineral. Whether it is lithium batteries or fuel cells, they are all necessary raw materials! That's fluorine.
Shandong Dongyue announced that it has conquered the sulfonic acid resin ion membrane technology used to manufacture the core material of fuel cells, and a production device with an annual output of 500 tons has been completed and put into operation. A major bottleneck in hydrogen fuel cell production has been solved, and China has become the second country in the world to possess this technology and industrialization capabilities. After eight years of scientific research, Dongyue Group’s 100% domestically produced perfluorinated ion membrane was successfully powered on for the first time in a 10,000-ton chlor-alkali plant. This marks that my country has become the third country in the world to possess the core technology and production capacity of chlor-alkali ion membranes. .
The raw material of ion membrane is fluorite. The main component of fluorite is calcium fluoride, which is a non-renewable strategic resource and the source of the development of fluorine chemical industry. The global fluorspar resource reserves are about 600 million tons, and my country's reserves account for 54%, ranking first in the world. Since the ion membrane electrolysis method has the characteristics of environmental protection and energy saving, the use of ion membrane electrolysis is the most advanced caustic soda production technology in the world today. Ion membrane electrolyzers and ion membranes are the core devices of chlor-alkali devices, and the key role is the perfluorosulfonate carboxylic acid ion membrane (perfluorinated ion membrane for short) installed on the electrolyzer.
Among the listed companies that use fluorite as raw material are Juhua, Duofuoduo, and Sanaifu.
Question 2: What are the uses of fluorite? Fluorite, also known as fluorite, is a mineral whose main component is calcium fluoride (CaF2), which contains many impurities. Ca is often Replaced by rare earth elements such as Y and Ce, it also contains a small amount of Fe2O3, SiO2 and trace amounts of Cl, O3, He, etc. Fluorite in nature often shows bright colors and has lower hardness than a knife. It can be used to prepare hydrogen fluoride: CaF2 H2SO4 = CaSO4 2HF↑; before artificial fluorite technology was mature, it was one of the materials for manufacturing optical glass used in lenses.
More than 7,000 years ago, the Hemudu people in China used fluorite for decoration. Fluorite is often made into various jewelry because of its large size and rich colors. However, its hardness is low. Do not wear it with natural crystals, as the crystal will scratch the fluorite! Fluorite mined directly from the mine contains certain radiation and cannot be placed in the bedroom!
Half of the world's fluorite production is used to make hydrofluoric acid, and then cryolite is developed and used in the aluminum smelting industry. Fluorite was used as the coolant (Freon) in refrigerators; in 1986, China's first generation of artificial blood also used fluorite. In recent years, scientists are developing fluoride glass, which may be made into new optical fiber communication materials, which can transmit across the 20,000-kilometer-wide Pacific Ocean without setting up a repeater station. The non-stick pans used at home have a layer of fluorine plastic coated on the bottom.
Chemical Industry
Another important use of fluorspar is the production of hydrofluoric acid. Hydrofluoric acid is produced by reacting acid-grade fluorite (fluorite concentrate) with sulfuric acid in a heating furnace or tank. It is divided into anhydrous hydrofluoric acid and aqueous hydrofluoric acid. They are both colorless liquids. , easily volatile, with a strong odor and strong corrosiveness. It is a key raw material for the production of various organic and inorganic fluorides and fluorine elements.
In the aluminum industry, hydrofluoric acid is used to produce aluminum fluoride, artificial cryolite, sodium fluoride and magnesium fluoride.
In the aviation and aerospace industries, hydrofluoric acid is mainly used to produce jet liquid propellant and missile jet fuel propellant. In the atomic energy industry, hydrofluoric acid is mainly used to produce UF4, which is then fluorinated to produce UF6, and 235U is separated by gas diffusion or gas centrifugation.
Hydrofluoric acid is the basic raw material of organic fluorine chemicals. It interacts with chloroform and carbon tetrachloride to produce fluorinated chlorine-containing hydrocarbons and fluorocarbons with low toxicity and high chemical stability. Used as refrigerants, aerosol accelerators, solvent polymer intermediates and fluorocarbon resins and elastomers.
Hydrofluoric acid reacts with carbon tetrachloride to produce Freon (usually represented by F). In addition to being used as a refrigerant, Freon is also widely used in sprays, fire extinguishing agents, fluoroplastics, etc.
In medicine, fluorine-containing organic compounds can also be used to manufacture fluorine-containing anti-cancer drugs, flucortisone-containing, fluorocarbon-containing artificial blood, artificial hearts and bones.
In the inorganic fluorination industry, pesticides, preservatives, protective agents, additives, fluxes and antioxidants can be produced.
The chemical industry has very high quality requirements for fluorite products. Generally, the CaF2 content is required to be between 93 and 98. Silica and calcium carbonate are harmful impurities and must be strictly limited. At present, the quality requirements of fluorite concentrate in my country are in accordance with the People's Republic of China and the National GB5690-85 "Fluorite Concentrate".
Building materials industry
Fluorite is also widely used in glass, ceramics, cement and other building materials industries, and its usage ranks second in my country.
Question 3: What is fluorite? Fluorite, also known as fluorite, fluorite powder, fluorite powder; is a mineral with an equiaxed crystal system, and its main component is calcium fluoride ( CaF2), contains more impurities. Ca is often replaced by rare earth elements such as Y and Ce. In addition, it also contains a small amount of Fe2O3, SiO2 and trace amounts of Cl, O3, He, etc.
Fluorite in nature often has bright colors, and some can fluoresce. Mohs hardness is 4, lower than steel, easy to scratch, brittle, sweet, astringent, and non-toxic; melting point: 1270-1350℃ . Density: 3.18g/cm3, refractive index: 1.434;
It can be used to prepare hydrogen fluoride: CaF2 H2SO4 = CaSO4 2HF↑; it is one of the materials for manufacturing optical glass used in lenses.
Question 4: What is Fluorite used for? Fluorite, also known as fluorite, is a mineral, also known as soft crystal, colorful gemstone, rainbow gemstone, dream stone, etc. Its main component is calcium fluoride (CaF2), which contains many impurities. Fluorite in nature often shows bright colors and has lower hardness than a knife. It can be used as gemstones and luminous pearls, but most radioactive substances are usually harmful to the human body.
Fluorite, also called calcium fluoride, is a common halide mineral. It is a compound composed of calcium fluoride, which is an important mineral for extracting fluorine. Fluorite comes in many colors and can also be transparent and colorless. Transparent and colorless fluorite can be used to make special optical lenses. Fluorite also has many uses, such as as a flux for steelmaking and aluminum production, used to make opal glass, enamel products, catalysts in high-octane fuel production, etc. Before artificial fluorite technology was mature, it was one of the materials used to make optical glass used in lenses.

Question 6: What is fluorite used for? Fluorite is the same as ordinary stones. It can be embedded in equipment to improve attributes. Fluorite is generally blue and can improve two attributes. However, fluorite Stones are stones that cannot be upgraded PS: Since gems must be set in specific equipment positions, for example, offensive stones cannot be set in jewelry, but offensive fluorite can be set in jewelry, which can additionally increase one's attack power
Question 7: What can fluorite tailings do for gold mines? After selecting the gold concentrate, a large amount of waste with no extraction value is left behind. This waste is not really without application value. In fact, it is a "composite" "Mineral raw materials. They mainly include non-metallic minerals quartz, feldspar, garnet, amphibole, pyroxene and clays formed by their alteration, mica-like aluminum silicate minerals and calcium-magnesium carbonate minerals such as calcite and dolomite. composition. The chemical components include silicon, aluminum, calcium, magnesium oxides and small amounts of potassium, sodium, iron, and sulfur oxides. The content of silicon and aluminum is relatively high, which lays the foundation for its use as raw materials for building materials.
According to the physical and chemical properties and composition of tailings, which have many similarities with building materials in terms of engineering properties, deep processing of tailings can produce materials with various functions, composite materials and glass products, etc.
Currently, based on the chemical composition, mineral composition and particle size characteristics of the tailings, building materials such as glass-ceramics, glass fiber, vitrified bricks, architectural ceramics, art ceramics, cast stone, cement, etc. are produced to make them additional The value is greatly improved.
