Magnets in pole position
Once regarded as an expensive last-minute add-on, magnetic separation technology is now seen as a crucial component in the processing mix
The growing popularity of magnetic separation technology has come about thanks to a triumvirate of improved permanent rare earth magnet material, a reduction in the price of magnetic raw materials and breakthroughs in magnetic design. Today, high intensity rare earth magnets of 45 MGOe are becoming commonplace and priced at levels that make them practical for a raft of applications. What is more, the pace of innovation shows no signs of abating. Magnets
