摘要：

A hematite has low grade, fine disseminated size andcomplex disseminated relations, which are refractory iron ore. Using SLon pulsating high gradient magnetic separator, induction intensity 8500Oe, pulsating 20mm stroke, stroke of 120 beats / min), a crude iron ore concentrates a grade of 35.93.%, the recovery rate of 82.39% is obtained through high intensity magnetic separation.( The final iron concentrate with TFe grade of 64.83%,yield of 14.55% and iron recovery of 35.74% from the raw ores with TFe grade of 26.29% was obtained, with the first stage grinding size being 50% -0.074mm and the second stage,95% -0.074mm.
