Over the past two years, Pretoria-based rare earth (RE) minerals refinery Rare Earth Refiners (RER) has designed, built and commissioned a demonstration plant for the green production of RE fluorides using a R15-million grant from the Technology Innovation Agency (TIA). REs, and especially neodymium trifluoride (NdF3), are extensively used in the production of permanent magnets used in electric vehicle (EV) and wind turbine electric motors.
