  • Processing of NdFeB magnetic material
    Patent number: 11915844
    Abstract: A method of processing NdFeB magnetic powder comprises: providing a source of hydrogenated NdFeB powder (101, 102, 103); feeding said powder into an inlet of a cyclone separator (104); separating the powder into an overflow enriched in Nd-rich grain boundary phase and an underflow enriched in NdxFeyBHz matrix phase particles (106); optionally feeding the underflow back into the inlet of the cyclone separator whereby to further enrich the underflow in the NdxFeyBHz matrix phase particles (108a); and collecting the underflow (108).
    Type: Grant
