In view of the resource characteristics and production status of Ekou Iron Mine of Taiyuan Iron & Steel (Group) Co Ltd, an experimental research was conducted to upgrade iron grade of the concentrate from the second-stage magnetic separation while reducing impurities therein. An optimized flowsheet consisting sequentially of grinding, low-intensity magnetic separation and reverse flotation was adopted in the experiment, resulting in a high-quality iron concentrate grading 69.93% TFe at a recovery of 93.08%, with a yield of 76.33%, while the SiO2 content was reduced to 1.63%.
