Fluorite, also known as calcium fluoride, is a common mineral halide. It is a compound. Its component is calcium fluoride, which is an important mineral extraction of fluorine. Under ultraviolet light, cathode ray irradiation or heating, it will have blue or purple fluorescent. Crystal is often a cube, octahedron or cube penetration twin, aggregate granular or massive. Light green, light purple or colorless, transparent, and sometimes rose red, white streaks, vitreous luster, transparent and opaque. Octahedral cleaves completely. Mohs hardness is 4, specific gravity is 3.18.
A, use the fluorite ore
Fluorite application is very extensive, with the progress of science and technology, wider and = wider prospect of application. At present is mainly used in metallurgy, chemical industry and building materials industry, secondly used in light industry, optics, sculpture and the defense industry. According to the use requirements, therefore, at present our country fluorite mineral products mainly has four big series of varieties, namely the fluorite ore and fluorescent (CFC) stone concentration, optical, sculpture, fluorite and fluorite ore fines.
1, the metallurgical industry
Fluorite is can reduce the melting point of refractory material, promote the slag flow, make the slag and metal fine separation, desulphurization and dephosphorization during the process of smelting, reinforced metal can be calcined and tensile strength etc. Therefore, it is widely used as flux steel smelting and ferroalloy production, iron craft and smelting non-ferrous metal. Smelting with fluorite ore generally require calcium fluoride content greater than 65%, friends of the [retail | collected] and the main impurity silica also has certain requirements, have strict limits on sulfur and phosphorus. The content of sulfur and phosphorus shall not be higher than 0.3% and 0.3% respectively. The quality of the products in accordance with the national standard of the People's Republic of China GB8216-87 "the fluorite ore is carried out.
2, chemical industry,
Another important use fluorite is produce hydrofluoric acid. Hydrofluoric acid is through acid grade fluorspar (fluorspar ore concentrate) react with sulfuric acid in the furnace or jar and produced, anhydrous hydrofluoric acid and hydrofluoric acid water, they are all a colorless liquid, volatile, have the exciting taste of intense and strong corrosion resistance. It is in the production of various organic and inorganic fluoride and fluorine element of key raw materials.
In the aluminum industry, hydrofluoric acid produces aluminium fluoride, synthetic cryolite, sodium fluoride and magnesium fluoride.
In thespecial andspecial industry, hydrofluoric acid is mainly used to produce jet liquid propellant, propellantspecial jet fuel. In the atomic energy industry, hydrofluoric acid is mainly used to make UF4, then through im fluorine into UF6, centrifugation separation by gas diffusion method or gas 235 u.
Hydrofluoric acid is the foundation of organic fluorine chemical raw materials, it is through interaction with chloroform and carbon tetrachloride, the production of small toxicity, high chemical stability of the fluorinated chlorine hydrocarbon and fluorocarbon, refrigerant, air sol promoter, intermediates and fluorocarbon resin and solvent polymer elastomer.
Second, the fluorite ore reserves
Fluorite is mainly produced in hydrothermal veins. Colorless transparent fluorite crystals are found in granite pegmatite or fluorite veins geode. At present the most main source of fluorine fluorite reserve-production ratio decreased, the main fluorite resources consumption countries and regions, our country to strengthen control over the export of fluorite, fluorite prices rising gradually.
Fluorite ore worldwide distribution set, recoverable reserves in China. According to the U.S. geological survey data, fluorite resources distribution is relatively concentrated around the world. By 2009, the world based reserves of 470 million tons of fluorite, recoverable reserves of 230 million tons, including South Africa, Mexico, China and Mongolia fluorite deposits in the column of the world's top four, the four countries can mines account for about 45% of the world, and as a major consumer of fluorite resources such as the United States and Western Europe has dried up.
In 2009, our country based reserves accounted for 23.4% of global reserves based on fluorite, fluorite proven recoverable reserves of 21 million tons, only 9.13% of the world's reserves, far less than 41 million tons and 32 million tons of South Africa and Mexico, among them, the Hunan, Inner Mongolia, and Zhejiang foundation reserves accounted for 38.90% of the total domestic, 16.70% and 16.10%, other provinces was only 27.80%.[gathering of friends of the retail.] although fluorite resources foundation is abundant in China, but only about 21 million tons of recoverable reserves, less than 10% in the world. China fluorite ore grade in 35% 40%;Only 30 million tons, one of 65% or more rich ore accounted for about 23.8% of the reserves. And less than 10 million tons of 80% or more the high grade diamond. All kinds of fluorite ore deposit, mines have been found about 874.Global reserve-production ratio is only 38, the reserve-production ratio is 6.According to the current fluorite recoverable reserves and the annual output of 2008 estimates, the global fluorite reserve-production ratio is only 38, reserve-production ratio has dropped to 6 in China.
Limited fluorite export prices in China, as a leading exporter of fluorite, our country has been taking measures to protect domestic fluorite resources, such as quotas export of fluorite, from export tax rebate to the tariffs, total amount control of fluorite ore mining, in principle, no longer accept new fluorite ore prospecting and exploitation of application for registration, etc.
Extracted from apatite fluorine is one of the ways to the future for fluorine resource; Can protect gradually reduce the fluorite ore resources; Development of advanced containing fluorine meticulous chemicals will be domestic fluorine chemical industry is the inevitable way out.
Three, fluorite ore prospect analysis
As one of new chemical materials, fluorine chemical industry in the 12th five-year plan single row a special planning. Planning proposed mandatory resources integration, and realize the basic stop exporting fluorite, hydrofluoric acid, exports more than half. The main composition of fluorite is calcium fluoride, is "is used and the non-renewable resources. Fluorite deposits in our country as the half of the world, proven recoverable reserves is only 1/10, and the yield is up to 1/2.Because resources are scarce, since 1999 the fluorite export quota system, but the fluorite is still in a large number of exports. Direct export of fluorite and disguised totaled 10.95 million tons, mainly fluorite resources provinces of our country accounts for about 8.4% of proved reserves. For fluorine chemical industry the 12th five-year plan put forward the export structure optimization goal. In addition to limit exports, is also brewing for fluorite resources to consolidate and strengthen the control of resources, the basic idea is to resources controlled by the state, concrete as an integration of leading role is a large state-owned enterprises. With state-backed fluorine chemical industry enterprises including China chemical industry, China's sinochem, JuHua co, three love rich, etc., including JuHua shares with three rich love is listed companies./ friends of retail, collect, authorities say, fluorite situation is similar to rare earth industry, will follow the rare earth policy introduced, time is expected in the first half of 2011.Due to fluorine chemical industry belongs to the law of the People's Republic of China regulations on monitored and controlled chemicals in category iv MCCS, and the future policy adjustments, production need to license system.
In the control of resources at the same time, the fluorine chemical industry the 12th five-year plan is put forward, and better play to the resource advantage, implementation to resources in technology, promotes our country by industry giants to industrial powerhouse.
