This project seeks to recycle neodymium and dysprosium from used neodymium-iron-boron, NdFeB, permanent magnets. Our alternative recycling strategy is based on a method developed by Dr. Eric Schelter of the University of Pennsylvania Department of Chemistry and his research group. This process involves the use of a novel tripodal nitroxide ligand, H3TriNOX. The proposed process design converts used NdFeB magnets to neodymium and dysprosium. The goal production of neodymium oxide is 126,000 kg/year and of dysprosium oxide is 14,000 kg/year, which would cost $12,500,000 with the current price rate of neodymium and dysprosium. Based on the results of the economic analysis, this project would be unprofitable in the near future.
