METHOD FOR RECOVERY OF Nd2Fe14B GRAINS FROM BULK SINTERED Nd-Fe-B MAGNETS AND/OR MAGNET SCRAPS BY ELECTROCHEMICAL ETCHING |
| abstract |
The invention relates to a method for recovery of Nd 2 Fe 14 B grains from bulk sintered Nd—Fe—B magnets and/or magnet scraps. In this method the Nd—Fe—B magnets ( 1 ) and/or magnet scraps are anodically oxidized using a non-aqueous liquid electrolyte ( 5 ), said anodic oxidation releasing the Nd 2 Fe 14 B grains ( 6 ) in said Nd—Fe—B magnets ( 1 ) and/or magnet scraps. The released Nd 2 Fe 14 B grains ( 6 ) 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. |
