Technique for recovering rare-earth metals from spent sintered Nd-Fe-B magnets without external heating
To selectively recover rare-earth metals with higher purity from spent sintered Nd-Fe-B magnets without external heating, we investigated the mechano-chemical treatment of spent sintered Nd-Fe-B magnet powder with a reaction solution of HCl and (COOH)2 at room temperature. The results of various exp...
