Application of Rare Earth Magnets in Mineral Processing

Recent advances in permanent magnet technology have led to the development of a new generation of permanent rare earth industrial magnetic separators. The excellent separation efficiency of these rare earth magnetic separators has reselted in them superceeding conventional electromagnetic high-intensity magnetic separators for many applications. One example of this technology is the Boxmag-Rapid Magnaroll magnetic separator which has been successfully installed for mineral processing applications. Research work is also presented, utilizing the Magnaroll in a novel application of removing ash and pyritic sulphur from coal samples.
