Boron ore is an important chemical mineral. By chemical processing boron ore can make boric acid, borax and widely used in many industries. At present China's boron mine mainly concentrated in LiaoNing province, the national boron ore production is about 487000 tons/year (passbook contains B2O3 for 12% of scale ore ability). In addition, there have villages, towns and individual small boron ore more than 100, these small ore does no fixed production capacity
Boron powder is an important chemical raw materials and alloy. LiaoNing province of china has rich boron resources, about 90% of the national boron chemical materials is by LiaoNing supply. But, after many years of development, the ludwigite ore in LiaoNing has faced with exhaustion, and a large number of occurrence of boron ore resources is for iron boron separation is difficult, but haven’t been use economically and effectively.
In recent years, China's boron ore and related products production is sustained growth. Internationally, the United States and Turkey have been are the two largest producers, the production accounted for more than 40% of the world's total output. China's output in the world share is very small.
China now existing about 30 chemical plants which produce borax, boric acid, production capacity of 200000 tons and 30000 tons respectively. Due to the rapid growth of boron market demand in recent years, metal powder suppliers dig the iron boron resources mining disorderly, the phenomenon of people take the rich and abandon poor becomes more and more serious, causing a tremendous waste of resources. The main problem existing is Chinese existing boron ore production mine keep recoverable reserves (szaibelyite ore) is not very much, and will be faced with exhaustion. The supply and demand to shield is very outstanding. With the development of Chinese national economy, the demand of boron sustained growth. According to the forecast of relative sectional statistic, borax and boric acid production, as the need of economic development, every year will with average speed grow by 6.25% and 6.50% respectively, there is no doubt that ludwigite ore production must also be synchronous growth, to meet the needs of the development of boron chemical industry, so that ludwigite ore supply and demand situation will more severe.
Therefore to solve the contradictions between the supply and demand china should take measures: one is the develop the WengQuan groove iron boron ore as soon as possible, boron mine reserves accounted for half of China's national reserves, weather the WengQuan groove iron boron ore develop or not,is very important to meet the future needs. The second is to strengthen boron mineral resources exploration, according to boron ore metallogenic regularity and metallogenic conditions, China boron ore resources has great potential. In the northeast China old mining area peripheral and deep continue to look for easy acquisition of szaibelyite type ore in China, the other two metallogenic belt should be also strengthen the study of metallogenic conditions, watch out for volcanic sedimentary type boron ore. The third is the comprehensive utilization of salt lake boron ore, the western qinghai-tibet salt lake boron ore have reserves of more than 1800 tons, accounting for 36% of the total, to the development and utilization of research will with very important significance.
For develop the demand of boron ore resources in Chinese boron chemical processing, in addition to strengthen geological exploration work, looking for new orefield, to those have identified a table inside lean ore, multielement common iron boron ore and uranium iron boron ore, should speed up its ore dressing, chemical industry, metallurgy various developmental research work, make these resources become boron chemical raw material base as soon as possible. In this respect, zhengzhou mineral resources comprehensive utilization research institute and domestic several scientific research units based on LiaoNing FengCheng WengQuan groove uranium iron boron ore comprehensive utilization research, use preliminary coarse grain cast tail, making iron boron mixed concentrate, reduced the magnesium boron ratio, further wet mention boron made breakthrough progress; In addition, the researchers developed "boron chemical separation method", the new technology of preparing boric acid, through the new technology application, will further easing the shortage of boron ore in china.
