Flotation System Transformation of Yuanjiacun Magnetite-Hematite Mixed Iron Ore
In order to improve the separation efficiency and iron recovery rate of flotation operation in Yuanjiacun Iron Mine of Taiyuan Iron and Steel Co.,Ltd.,aiming at the problems of poor desliming effect of feed ore,high iron grade of tailings and low scavenging efficiency of flotation system,on the basis of process flow investigation,the operation control logic optimization and process technical transformation are carried out.Through the transformation,the desliming effect of flotation feed is improved obviously,and the deslim-ing amount is increased by 2.14 times.The total iron grade of flotation concentrate is 65.19%,the recovery rate of iron is 80.94%,the total iron grade of flotation tailings is 17.16%,and the iron grade of tailings is re-duced by 5.35 percentage points.All the indexes of flotation meet the requirements of design indexes.
