Abstract: Several new models of SLon vertical ring and pulsating high gradient magnetic separators and their application in mineral processing companies to drop cost and raise efficiency were introduced.SLon-2250 applied in Yuanjiacun Iron Mine of Taiyuan Iron and Steel Company，made the tailings grade of high intensity magnetic separation dropped 1.70 percentage points and iron recovery raised 2.55 percentage points；With SLon-2000-1.3T applied in Lilou Iron Mine in Anhui Province and Dong'anshan Sintering Plant of Anshan Iron and Steel Company to process oxidized iron ores，iron recoveries raised by 6.92 and 4.28 percentage points，iron recovery raised 19.87 and 12.92 percentage points respectively；With SLon-2500 new model applied in Meishan Iron Mine of Shanghai Baoshan Iron and Steel company，the high intensity scavenging magnetic concentrate grade increased 1.91 percentage points，tailings grade of scavenging high intensity magnetic separation dropped 1.63 percentage points，iron recovery raised 3.82 percentage points；SLon-2000-1.5T，SLon-2500-1.5T and SLon-2500-1.8T have been successfully applied in feldspar and quartz purifying industry with good technical and economical results achieved.
