Semi-continuous calciothermic reduction and production of rare earth elements
Andrew Sherman of Terves leads the CMI project "Semi-continuous calciothermal reduction and production of rare earth elements"
In this project, Terves LLC, in collaboration with Worcester Polytechnic Institute (WPI), Ames Laboratory and Powdermet Inc., will develop and build a semi-continuous process capable of producing 99.9 percent purity neodymium (Nd) by converting neodymium oxide into a neodymium chloride (NdCl3) followed by calciothermic reduction to produce master alloys that can be used in the production of rare earth magnesium alloys and magnets.
