We already reported the separation and recovery process for rare-earth metals from Nd magnet scraps using molten salt electrolysis and an alloy diaphragm. This process was first applied to chloride melts, and the separation of Dy and Nd were investigated using Ni and Cu cathodic electrodes in molten LiCl-KCl-DyCl3-NdCl3 systems. The present study focused on Tb as a scarce element in scraps. As a first step, the electrochemical formation of Tb-Ni alloys was investigated in a molten LiCl-KCl-TbCl3 system at 723 K. Furthermore, separation of Tb and Nd was investigated using molten salt electrolysis and an a Ni electrode.
