Nevertheless, a wet-magnetic separation is suitable on the unsized material which contains a large portion of the material <75 µm size. Wet-magnetic separators which generate a sufficiently high magnetic force in the working space are desirable to extend the process of magnetic separation on the unsized ore minerals <75 µm size (Svoboda, …

Coal-based reduction and magnetic beneficiation. In commercial beneficiation practice [32], the feeding quality at real production stage is usually lower than the original ore in lab-scale. To mimic the real industrial iron beneficiation, also to optimize and facilitate the process, 5 wt % of surrounding rock was added.
