New technical specifications for slurry iron removal have been officially released. Higher purification requirements are set for micro-scale weak magnetic impurities contained in lithium battery cathode and anode materials, high-purity quartz sand and high-grade ceramic glaze, reaching ppb-level precision. Conventional separation equipment can no longer meet strict industrial standards. High-gradient wet electromagnetic separators serve as ideal solutions, steadily controlling iron impurities below 1ppm. Leading domestic manufacturers see their order volume surge by over 40% year on year.
