| Abstract: | The iron ore in Gansu is hematite deposit. The iron grade in crude ore is higher but refractory. After the hematite mineral of complicated occurrence state and thin particle was processed by reduction roast-thin magnetic separation technique, the grade and recovery of iron concentrate was low grade. For improving the grade and recovery of iron concentrate, the iron ore is processed by the high gradient magnetic separation technique when grinding fineness is thin. Under condition of the feed grade 50.82%, the results of the grade of iron concentrate 62.03 % and the recovery of iron 68.78 % is obtained. The refractory hematite is recovered successfully. |
