Recent advances in magnetic separator designs and …

magnetic separators may be wet or dry. High intensity dry magnetic separations are carried out with induced-roll (IRM) or rare-earth roll (RER) magnetic separators, though the latter is far more common (Dobbins, Sherrell 2009). The RER is known for efficient separations with weakly paramagnetic minerals, albeit it at somewhat lower capacity ...
