High purity rare earth concentrate successfully extracted from coal can be used in aviation and lighting

American scientists at the university of Kentucky successfully extracted from coal, close to pure rare earth concentrate is adopted by the environmental protection consciousness and cost effective way. After more than $7 million funding for the department of energy (doe) to obtain, chief researcher and mining engineering professor Rick Honaker can create the new material research. 'The U. S. department of energy project's main goal is to produce at least 2% of rare earth elements content of concentrate,' Honaker said, 'we have surpassed the goal. 'He said, the extraction process is successful recovery more than 80% of rare earth elements that exist in the feed. From the perspective of the whole of dry, concentrate containing more than 80% of the rare earth elements, and more than 98% of the rare earth oxides. In addition, the commonly used in national defense, in the field of high and new technology and renewable energy and neodymium yttrium accounted for more than 45% in the concentrate. At the same time, through a new recovery process, the effective separation of scandium and other elements. The rare earth elements is often used in aviation and lighting area, can condense into individual products. Honaker team is moving to a quarter of an hour of tons of rare earth recovery pilot plant project, the breakthrough technology is only part of the project.
