摘要
为了提高铁精矿品位,降低铁精矿中其它脉石矿物的含量,包钢选矿厂在细筛后增加淘洗机精选作业,并进行了淘洗机给矿浓度、磁场强度、水阀开度、底阀开度试验,将铁精矿品位从56.8%提高到67.0%,铁回收率为93.42%,同时达到了提质降杂的效果。
In order to improve the grade of iron concentrate and reduce the contents of other gangue minerals in iron concentrate,the concentration with wash mill is added after finely sieving in Concentration Plant of Baotou Steel.Moreover,such tests as feeding concentration of wash mill,magnetic field intensity,opening of water valve and bottom valve are carried out.Finally,the grade of iron concentrate increases from 56.8%to 67.0%,recovery rate of iron is 93.42%so that the effects of quality improvement and impurity reduction are achieved.
