| 摘 要： | 对海南矿业深部赤铁矿石进行了矿石性质研究，并根据矿石性质进行了干式强磁选预选、跳汰预选试验研究。对原矿采用分级、干式强磁选、跳汰重选可以预先获得产率35.26%、铁品位55.35%、回收率49.85%的高炉块矿，抛出产率21.61%、铁品位10.83%的块状尾矿，入球磨矿量可大幅减少、节能减排效果明显。

| Abstract: | The ore properties of deep hematite in Hainan Mining are investigated. According to the properties, such tests as pre-concentration by dry high intensity magnetic separation and jigging are made. Lump ore with yielding of 35.26%, Fe grade of 55.35%, and recovery of 49.85% are primarily obtained from run-of-mine by classification, dry high intensity magnetic separation and jigging. Meanwhile, lump tailings with discarding rate of 21.61% and Fe grade of 10.83% are obtained. By this method, the amount of ores for grinding can be significantly reduced with obvious energy saving. |
