Rare earth elements are an easy-to-find, hard-to-refine resource critical for everything from magnets and electronics to batteries and catalysts for chemical reactions. Since the 1980s, a race has been on between the United States and China for dominance of the rare earth element market — and the United States is losing.
New research out of Northeastern University has discovered a new way to extract rare earth elements out of coal tailings, the cast-off soil and rock left behind by coal mining. Using a chemical treatment and a specially designed microwave reactor to control the temperature, the researchers have doubled the extraction levels previously possible.
