OAK RIDGE, Tenn., Aug. 10, 2015—The Critical Materials Institute is celebrating its first commercial licensing agreement, a single-step technology to recover rare earth elements from scrap magnets.
The membrane solvent extraction system was developed by the U.S. Department of Energy's Oak Ridge National Laboratory and Idaho National Laboratory, partner facilities of CMI.
A new recycling method developed by scientists at the Critical Materials Institute, a U.S. Department of Energy Innovation Hub led by the Ames Laboratory, recovers valuable rare-earth magnetic material from manufacturing waste and creates useful magnets out of it. Efficient waste-recovery methods for rare-earth metals are one way to reduce demand for these limited mined resources.
Karl A. Gschneidner and fellow scientists at the U.S. Department of Energy’s Ames Laboratory have created a new magnetic alloy—a potential replacement for high-performance permanent magnets found in automobile engines and wind turbines--eliminates the use of one of the scarcest and costliest rare earth elements, dysprosium, and instead uses cerium, the most abundant rare earth.
“The textbook said we should see slow, gradual and random. But what we saw? BOOM! Fast, explosive and organized!” said Michael Tringides, physicist at the U.S. Department of Energy’s Ames Laboratory and a professor of physics and astronomy at Iowa State University.
Tringides is talking about the unusual atom movement he saw when they dropped a few thousand lead atoms onto a flat, smooth lead-on-silicon surface, all at low temperatures, and looked at an area just one-twentieth the width of a human hair
