Recently, it has been reported that U.S. scientists have extracted nearly pure rare earth concentrates from coal, which can be used for aviation and lighting. The rare earth concentrates contain more than 80% rare earth elements. What is the specific situation? Like it? Scientists at the University of Kentucky in the United States have successfully extracted nearly pure rare earth concentrates from coal using environmentally conscious and cost-effective methods. Rick Honaker, principal investigator and professor of mining engineering, said the extraction process successfully recovered more than 80% of the rare earth elements present in the feedstock. From a dry, monolithic perspective, the concentrate contains more than 80% rare earth elements and more than 98% rare earth oxides. In addition, neodymium and yttrium, commonly used in defense, high-tech and renewable energy, account for more than 45% of the total concentrate. At the same time, scandium is effectively separated from other elements through this new recovery process. The rare earth elements commonly used in aviation and lighting, can be concentrated into separate products.
