New Process Takes Simpler Approach to Rare Earth Magnet Recycling A new recycling process developed at the U.S. Department of Energy’s Critical Materials Institute (CMI) turns discarded hard disk drive (HDD) magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable [...]
Geomega recycle USA Rare Earth's waste Quebec-based mining technology firm Geomega Resources Inc plans to recycle rare earth-containing production waste produced by critical minerals producer USA Rare Earth. Geomega will recycle the production waste from USA Rare Earth's future production of sintered neodymium iron boron (NdFeB) permanent magnets (sintered neo magnets) in the United States. [...]
Progress in Recycling of Sintered NdFeB Magnet Wastes Significant efforts have been put into the recycling of bulk sintered NdFeB magnet wastes around the world in the past decade because bulk Nd–Fe–B sintered magnet wastes are valuable secondary rare-earth resources. There are two major facts behind the efforts. First, the waste magnets contain total rare-earth [...]
Recycling of Additively Printed Rare-earth Bonded Magnets In this work, we describe an efficient and environmentally benign method of recycling of additive printed Nd−Fe−B polymer bonded magnets. Rapid pulverization of bonded magnets into composite powder containing Nd-Fe-B particles and polymer binder was achieved by milling at cryogenic temperatures. The recycled bonded magnets fabricated by warm [...]
Rare-earth Recycling Magnetic Idea, recycling rare earth metals, rare-earth recycling invention, Recycle rare-earth elements and magnets Recycling keeps paper, plastics, and even jeans out of landfills. Could recycling rare-earth magnets do the same? Perhaps, if the recycling process can be improved. Scientists are working to more effectively remove the neodymium, a rare earth element, from [...]
