A facile method for the simultaneous recovery of rare-earth elements and transition metals from Nd–Fe–B magnets†
Abstract
A green and facile electrochemical method for Nd–Fe–B PM recycling was developed. The proposed procedure enables a selective REE recovery and a simultaneous Fe metal deposition in only two processing steps, with the total re-use of the electrolyte. The proposed procedure thus avoids the formation of solid Fe-based waste and wastewater discharge.
