Turkey is rich in boron resources, borideproduction ranks second in the world, reaching 1.18 million tons, mostly forexporting; Russia has 227,000tons, Argentinahas 7.8 tons. Including China,these countries have reserves different amount of boron resources. According tometal powder exporter, Western Europe and Japanand some other developed countries were lack of boron resources, mostly relyingon imported ore or borax, boric acid to deep process into other borides.Afternearly 50 years of development, Chinahas basically established a boron mining, boron processing, boron and boronfine chemical new materials, production and other complete industrial system.Currently, the annual boron ore production is 1.4 million tons (standard ore),borax production capacity is 500,000 tons (in 2003, the production is 385,000tons), boric acid production capacity is 200,000 tons/year, the output isaround 60,000 tons/year. After 2003, Qinghai, Shandongs boronindustry was getting rapid development.Chineseboron industry is based on produce boron borax and boric acid. Chinese borax ismainly used in glass and enamel industries. In recent years, the demand of Chineseborax is increasing, in 2001 it was 327,500 tons, in 2002 it was 352,400 tons,in 2003 it was 385,000 tons, in 2004, more than 400,000 tons. In 2005, Chinesetotal demand of borax was more than 420,000 tons. At present, Chinese annualoutput of boron stone is about 1.4 million tons (standard ore), boraxs annualproduction capacity is 500,000 tons, the annual output capacity of boric acid is200,000 tons. Boric acid is mainly used for glass and light. Nearly two years,boride production enterprises through adjusting the product structure, improvethe high value-added boron fine chemical products production, boric acids demandwas increased, has been increased from 50,000-60,000 tons to 80,000 tons, anaverage annual increase speed is up to 6.5%. By 2010, Chinese boric acidconsumption has reached 15 million tons.Chineseboron ore are mainly the ascharite, lower grade (boron oxide, 12% -14 %), atpresent, the borax production is used CO2-soda method. Boric acid are generaluse sulfuric acid step, using higher grade boron and magnesium ore in Tibet, Qinghai,Liaoning as raw material. Nearly two years, some companies in Shandongregion using the Tibet, Qinghais ascharite to produceboric acid (one-step) were put into industrial production, and some of them arereached an annual output of 5,000 tons.China is now able to produce positive borate, metaborate, perborate,fluoroborate salts, boron halides, boron hydrides, boron powder, boron whiskers and other boride, have eleven series, 40 kinds, nowthe largest varieties have calcium borate, sodium perborate, zinc borate, boroncarbide and other types. The world's proven reserves boron ore has about 335million tons, mostly distributed in the Western Hemisphere, the United Statesis the most concentrated. Chinese proven boron reserves have 50 million tons.Among them, half of them are szaibelyite magnesium iron and boron mixed ore,salt lake brine and solid boron is about 2,000 tons, and the facilitate explorationascharite mineral is less than 300 tons. Therefore, less, low grade, highimpurity content is the weak point of Chinese boron resources. According to theChinese boron resources, from the 1950s, Chinese enterprises are using two-stepmethod to produce boric acid, in recent years begun to take one-step production.Source:http://www.mhcmp.com
