Abstract
The invention relates to a method for recovery of NdFeB grains from bulk sintered Nd—Fe—B magnets and/or magnet scraps. In this method the Nd—Fe—B magnets () and/or magnet scraps are anodically oxidized using a non-aqueous liquid electrolyte (), said anodic oxidation releasing the NdFeB grains () in said Nd—Fe—B magnets () and/or magnet scraps. The released NdFeB grains () are collected during and/or after said anodic oxidation. The proposed method allows a more environmental friendly and cost-effective way for recycling EOL Nd—Fe—B magnets/Nd—Fe—B magnet scraps.
