Recent advances in magnetic separator designs and applications

Magnetic separation equipment has long been used to upgrade and beneficiate a wide variety of minerals and materials. Over the years, significant advances in both wet and dry magnetic separators have improved their operability and separation performances, broadening their use. However, certain areas of weakness still remain, including: fine particle processing, high temperature limitations and suboptimum separator designs. This paper will provide a brief look at existing technology and highlight some key areas where room for improvement exists. Recent novel magnetic separator technology developments aimed at addressing these limitations will then be explored, and substantiating data discussed. The recent advances in magnetic separator developments highlighted in this paper show that, through continued development, traditional processing obstacles can be hurdled allowing for more efficient and robust minerals processing solutions.
