Jiangxi Xunwu County full use of resources , on the pretext of the power of science and technology to achieve a rare earth mineral processing intensive processing and transformation and upgrading of enterprises , as well as efforts to promote deep processing of rare earth mineral processing enterprises to improve their market competitiveness.

The county invested 1.08 billion yuan construction of five rare earth deep processing projects to support the rare earth and other mineral processing enterprises in technological expansion ; encourage enterprises and universities , research institutes marriage cooperation ; developing series of preferential policies and measures to encourage enterprise and research institutes to establish R & D center , to accelerate the pace of technological transformation of enterprises .

Cooperation with research institutes to promote the county's resource utilization and industrial technology research and development projects , the annual use of waste tailings over 20,000 tons of rare earth production of ceramic products as the main source of materials, direct economic benefits more than 100 million yuan .

While the introduction , the use of new technology to enhance the economical use of resources . Hengyuan Technology has been the introduction of rare earth deep plus many other businesses, and the country is important to establish Jiangxi Rare Earth New Material Industrial Base and green power technology park. Especially rare earth deep processing project has been included in the Ministry of Industry and Information Technology , Ministry of Finance, Ministry of Land and exploitation of rare earth integrated pilot projects to support industrial and technological achievements , is expected to be added after the project is put into the annual output value 4,000,000,000 yuan , profits of 600 million yuan .

With the welding materials industry continues to progress and development of the reliability and stability of the electrode materials made ​​more stringent requirements. Multiple rare earth oxides with its high melting point, low electron work function , excellent thermal electron emission performance, as the main material instead of thorium tungsten and tungsten electrodes for welding small size had succeeded in replacing thoriated tungsten ; But in exchange argon arc welding arc remains poor, life is short so inadequate . In general, the composite rare earth tungsten electrode arc characteristics are superior to rare earth element tungsten electrodes , while the composite rare earth tungsten electrodes , the ternary complex sound in the binary complex .

In the late 1980s , a group of Japanese scholars in the development of new tungsten electrode materials has made some progress , especially studied a series of complexes of rare earth tungsten electrode material . Composition of the electrode design, performance comparisons and mechanism of a lot of work , find binary complex rare earth tungsten electrodes can improve the performance . Osaka University scholars composite ( binary, ternary ) rare earth tungsten electrodes have been studied , a preliminary study showed that: in terms of binary rare earth tungsten electrodes , CeO2: Y2O3 = 1:3 (W-CeO2 = 0. 5%, W-Y2O3 = 1.5%); ceria : lanthanum oxide = 1:1 ; lanthanum oxide : yttrium oxide = 1:3, the three components of the tungsten electrode performance is more prominent, especially in endurance wherein 1:3 (La2O3 + yttria ) tungsten arc 4h (180A) remain good performance , the durability performance of the arc 10h are acceptable , which is more than rare earth element to be much stronger durability of tungsten electrodes . For triad earth tungsten electrodes , the best ratio of rare earth oxides of cerium oxide : lanthanum oxide: Y = 1:1:3 , a good operational performance of this electrode sustainable 10h (180A), than other two yuan tungsten electrode and cell - lanthanum electrode (10h melting severe) ends better shape retention . Rare earth oxide in the composite tungsten electrodes , the lowest operating temperature of these electrodes , the highest emission efficiency : lowest electron work function , ie transmission is supreme , the overall performance is more prominent. Beijing University and Beijing Tungsten & Molybdenum Material Factory cooperative research binary complex rare earth tungsten electrodes , as well as ternary complexes of rare earth tungsten electrodes that composite tungsten arc welding electrodes and processes are better than single rare earth tungsten electrodes and thoriated tungsten electrodes .

To further promote the special treatment of rare earth industry to combat illegal behavior of rare earth , recently , the Ministry prepared to " invoices " as a clue, involving the domestic rare earth mining, smelting and trading enterprise for large-scale separation of the special investigation, one by one registration , established in accordance with the inspection of rare earth enterprise management " black list " and categorized for management, to establish long-term regulatory mechanism .

With the previous inspection have other is that this rare remediation objects , including not only Baotou , Ganzhou , Guangdong and other places of rare earth minerals separation of rare earth mining and smelting enterprises, some of Shanghai , Beijing and other rare-earth trading companies are also the scope of the examination , a total of 1594 households.

MIIT said that once found RE illegal activities, in addition to be shut down by local authorities to rectify such punishment, the rare earth companies will be registered into the "blacklist" , including business executives , will become the Ministry of Industry and local governments focus on monitoring objects , and local government accountability linked to prevent illegal rare earth " resurgence ."
