Abstract: Diaojuntai Concentrator used 15 SLon-2000 high intensity magnetic separators to replace the Shp-3200 flat-ring high intensity magnetic separators in its original process composed of continuous grinding-low intensity magnetic separation, high intensity separation and reverse flotation. After the technical transformation, the process consisting of staged grinding, coarse and fine size-classified separation by gravity separation, magnetic separation and anionic reverse flotation uses 15 SLon-2000 high intensity magnetic separators and 15 SLon-2000 medium intensity magnetic separators for tailing discarding by desliming and at coarse size respectively. These SLon magnetic separators have played an important role in reducing fine metal loss, improve metal recovery, creating a good condition for reverse flotation and reducing middling regrinding load, thereby providing guarantee for the a continuous achievement of excellent production performance of Diaojuntai Concentrator.
