Pictured are oxides of the magnet rare earths neodymium, praseodymium, and dysprosium that have been processed with sulfidation technology. The violet regions are neodymium-rich sulfide, the green are praseodymium, and the orange are dysprosium-rich sulfides and oxysulfides.

Massachusetts Institute of Technology researchers have devised a unique method to help curb the looming shortages of critical minerals and metals by making it easier to separate them from ore and recycled materials with a chemical process called sulfidation.

This processing technique, as written about in a paper they published in the journal "Nature," allows the metals to remain in solid form a...
