A novel neodymium oxide (Nd2O3) extraction process was devised and its feasibility was demonstrated in order to establish an environment-friendly process that combined scraps containing valuable metals. The newly developed device can simultaneously accomplish continuous extraction of Nd oxide from scraps, the extraction of Nd oxide of 98 percent purity was directly recovered from magnet scraps under certain conditions. Major process parameters and extraction temperature, were investigated in order to evaluate the optimum conditions. The results of the investigated process indicated the possibility of extracting Nd oxide directly from magnet scraps.
