Rare earth luminescent materials research breakthrough

Recently, the Chinese Academy of Sciences Changchun should be light and Sichuan Sony Corporation co-developed "light Yuhui Shou life controllable LED light rare earth materials research and development and in the semiconductor lighting application" project, through the Chinese Academy of Sciences in Chengdu, the results of identification. The rare earth luminescent materials effective solution has not been possible to break the international exchange of LED lighting strobe problem, reached the international advanced level, making China the world's only mastered through the production of rare earth phosphors low strobe AC LED product technology in the country.

Changchun Institute and the New Source Co., Ltd. in 2006 in cooperation new AC LED lighting technology research and development. New rare-earth materials and the existing LED light LED, compared with a low heat, energy conversion efficiency, small size and other advantages, we can improve the service life of more than twice the energy consumption and costs were reduced by 15% and 20%. The achievement won the 2012 British Institute of Engineering and Technology "energy innovation" and "Built Environment" two award nominations, and has received three Chinese invention patents, three PCT international patent application has entered a number of countries the trial phase.

Japanese rare earth mine waters of Southern Torishima exclusive exploration rights

METI announced that Japan has received 20 international agencies, may do in the next 15 years on the South Bird Island in the Pacific waters of an exclusive rare seabed exploration. METI said the survey shows that in the South Bird Island, about 600 km southeast of 1000-2000 meters of high seas bottom under a large quantity of rare metals, including extremely important rare earth resources. METI commissioned Japan Oil, Gas and Metals Company to the "International Seabed Authority" for the high seas in the formal exploration, confirmed reserves and so on. "International Seabed Authority" on the 19th approved the application, Japan will be the next 15 years for a total of about 3,000 square kilometers of ocean exploration.

China's rare earth products to get rid of dependence on imports

To get rid of dependence on rare earth products imported from China, the United States is the country looking for abandoned mine in the residual elements, has a rare earth mine excavation, which may be an impact on China's rare earth-related enterprises.

The Associated Press reported on Sunday that as lanthanum and lutetium like 15 kinds of rare earth elements during the early gold rush has been found, it has not been without attention. Until recent decades, the rapid development of electronic equipment to promote the demand for these elements are also increasingly strong, these elements allow the battery to become more portable, allowing fluorescent screen lights up for the touch screen to add color.

USGS Mineral Resources official Larry Stewart Menezes said: "If these waste products proved to be valuable, then it is a win-win situation, on the one hand we can finally get rid of dependence on China, and secondly we You can also find the elements had not seen before. "

"Before we did not feel that their mining is sufficient to meet demand from China, and we think that earth became a weakness of the U.S. economy," USGS Mineral and Environmental Resources Science Center Director Ian Ridley said.

Two years ago, imported from China rare earth prices began to rise, the price of neodymium per kilogram from 2009 up to 2011 $ 15 500 dollars, the price of dysprosium oxide from 2010 to 114 U.S. dollars a kilogram rose to $ 2,830 in 2011 .

Price increases forced the U.S. government into emergency mode, the U.S. Geological Survey and the Department of Energy to send geologists to go searching all over the country. Now the United States is only a rare earth mine output, and its address is located at the southern California desert Yamaguchi. Part of Molycorp's mine is expected this summer, this can produce 20,000 tons of rare earth, including polished telescope lens for ceria.

Meanwhile, at the University of Nevada, Reno and the University of Colorado School of Mines, the U.S. Geological Survey researchers are using laser irradiation from the instrument during the Gold Rush in the excavated rocks and minerals to detect the presence of rare earth elements.

"We are now revisiting history," U.S. Geological Survey expert in charge of the project proposed grid representation Aaron Kay said.

Perpetrators of illegal mining of rare earth rather be jailed and fined

To seek profits, without obtaining a mining permit in case of unauthorized exploitation of rare earth ore, mineral resources and ecological environment caused serious damage, case proceedings, the defendant Xiong, FAN green Guanhuzeren willing to take ecological restoration initiative to pay to restore vegetation margin. Recently, Ninghua People's Court case with the illegal poaching of rare earth ore verdicts, judgments defendant Xiong, FAN guilty of the crime of illegal mining, were sentenced to three years imprisonment, suspended for four years and fined 120,000 yuan.

June 2011 to November, the defendant Xiong, FAN discuss with others illegal mining of rare earth ore division, the defendant Xiong responsible RBI Foreign mining sites and on the uphill intersection lookout, the defendant FAN dredge socially responsible relationship, and the remaining duties everyone together in the illegal exploitation of Xiang River Ninghua rare earth ore. November 2011 that illegal mining mines destroyed by the river Xiang government. By the Fujian Provincial Department of identification, due to undocumented illegal mining of rare earth mineral resources resulting value of about 700,000 yuan.

Ninghua Court held that the defendant Xiong, FAN together with others to violate the provisions of the Mineral Resources Law, without obtaining a mining permit, unauthorized exploitation of rare earth minerals, causing serious damage to mineral resources, their behavior had constituted the crime of illegal mining. Given the defendant Xiong, FAN justice after a good attitude, and voluntarily pay the deposit to restore vegetation, as appropriate sentences, it made ​​the decision.

Illegal poaching of rare earth mineral resources, mineral resources, not only seriously damaged, but also the impact on the local ecological environment, resulting in soil erosion. To repair damage in the ecological environment of crime, the Court has been committed would rather carry out ecological compensation mechanism of public justice, and Forestry jointly promote the establishment of judicial guarantees Ninghua green ecological support association, fusion funding to re-establish a base model green management and protection, Soil Conservation service for further accelerating the construction of ecological civilization. Green replant bear complex legal obligation to pay the defendant's re-plant complex Green Ecological Association margin is one of the sources of funds to replant the current complex ecological associations rely on two bases in green management and protection of ecological restoration, and achieved good results.
