Liangshan rare earth extraction technology to achieve scientific and technological breakthroughs

"Recently, the State of Sichuan Liangshan Yi Autonomous Prefecture of 973 major science and technology plan "rare earth extraction and separation processes to expand the test" project through the acceptance of the Expert Group. The project by the Sichuan Jiangxi Copper Co., Ltd. Xing Fang rare bear, the Group by the Chinese Academy of Sciences Zhang Hongjie, China Rare Earth Industry Association Secretary-General Wang iron, seven well-known experts.The Group believes that the breakthrough in the international project on the six original process technology, to capture the original process unreasonable key technologies, marking the Liangshan rare earth extraction process advanced in the world.
Rare Earth Extraction Separation Process pilot project to expand the use of independent synthesis Cextuant230 (the world's first sevenmonths extracting agent), replace expensive imported from the United States Cyanex923 to extract light rare tetravalent cerium and thorium, superior performance. After 50 repeated trial production, to expand the test and achieved consistent with the findings of the effect. The successful implementation of cerium fluoride, thorium while recovering radioactive thorium and separation and recovery, to prevent contamination of radioactive waste from the source.Meanwhile, the technology uses low-cost fixed-fluoro-tetravalent cerium to achieve recovery and value-added fluorine resource utilization, eliminating the fluorine pollution. Extraction recoveries tetravalent cerium nearly 80 percent , thorium extraction recovery reached 95 %, and the successful implementation of recycling waste extraction solvent recycling.
　　Expand the test results show that the use of autonomous syntheticCextrat230 extraction agent is a major innovation in Liangshan Prefecture extraction of rare earth industry process technology, not only greatly reduce the production costs, but also a significant reduction in pollutant emissions, with significant economic, environmental and social benefits.
　　Rare Earth Extraction Separation Process expand the successful implementation of the pilot project for rare earth extraction process has opened up a new path, it will completely optimize existing processes, to provide a reliable parameter for further research and development of new technologies and the development of separate functional materials, rare earth industry to become cost efficiency transformation and upgrading, speed up the development of new impetus"

Chinese obviously working to improve cost efficiency HRE, to produce an economic product at the new norm of dramatically reduced prices. Simply getting harder & harder for remote, < 1% grade, hard rock, (underground???) deposits to compete.
