| Abstract: | Yunnan iron tailings with the grade of 17.11%,the optional iron mainly in the form of magnetite, followed by hematite, limonite, fineness is -0.074mm 42.51%, iron ore concentrate product with the yield of 11.48%, the grade of 58.65% and the recovery rate of 39.35% can be obtained by using the process of low-intensity magnetic and high-intensity magnetic tailing, re-grinding, low-intensity magnetic and shaking table gravity separation, to achieve the recovery of iron. |
