Abstract
In this study, the main aims were to recovery iron from iron tailings containing high silicate and reduce the tailing grade by using combined separating technology. Experimental studies were carried out on the iron tailings in Dahongshan samples, which contain 27.78% of iron. Through the experiment, the first is pre-classification by high-frequency vibrating, and then the iron is recovered by strong magnetic separation of one rough, one scavenger and a gravity concentrating with Slon and chute. The iron concentrate which the grade of Fe is 53.08% and the recovery of 68.45% is obtained and the grade of tailings reduce from 27.78% to 13.80%. Iron tailings get a comprehensive utilization, which has a better effect.
