Solvometallurgical process for the recovery of rare-earth elements from Nd–Fe–B magnets

[Display omitted] •Nd–Fe–B magnets completely dissolved in pyridinium chloride (PyHCl) within 10 min.•Preliminary roasting of the Nd–Fe–B magnets is not required, just milling.•Leaching in pure PyHCl at 165 °C avoided the consumption of other solvents.•Neodymium and dysprosium were extracted by diff...
