浮选分离某磁铁矿和富含磁黄铁矿的试验研究

Experimental Research of Separating Magnetite From Strongly Magnetic Pyrrhotite by Flotation

介绍了磁铁矿的矿石性质、分离浮选的试验研究结果。试验结果表明 ,采用以丁基黄药为基料的复合捕收剂 ,经先浮选后磁选工艺流程 ,可将铁精矿品位提高到 6 6 %以上 ,硫含量降至 0 3%以下 ,改变了该矿因产品硫含量过高而停产的局面。

The ore properties and the experimental research of flotation of a magnetite ore are described. The test results showed that using a technological flowsheet of flotation followed by magnetic separation and using a compound collector that has butyl xanthogen as the base, could raise the grade of the iron concentrate to over 66% and reduce the sulphur content of the concentrate to below 0.3%, which saved the mine from shutdown due to too high a sulphur content of its product.
