Since 2006, four main efforts can be observed in magnetic separation literature: (a) beneficiation of rare earth ores, (b) separation of weakly magnetic minerals, (c) purification of non-metallic ores, and (d) processing of slags and slurries. For these purposes, it is suggested to use advanced drum separators and roll separators with rareFlotation has been widely used in the beneficiation industry and the flowchart of the flotation experiments (Fig. 1 c).
