摘要： 为了使某矿山贫磁赤铁矿资源得到合理的开发利用，针对现开采部位矿石的性质和可选性问题，进行了工艺矿物学和可选性试验研究。试验结果表明：采用弱磁、强磁—阴离子反浮选工艺可得到精矿铁品位68.55%、精矿产率36.41%、金属回收率79.92%、尾矿品位9.86%的较好选别指标，说明矿石的可选性较好，为该矿石的合理开发利用提供了可靠的技术依据。

Abstract: In order to make a reasonable development and utilization of lean maghemite resources in a certain mine,a technological mineralogy and selectability test research was carried out for the nature and selectability of the ore at the current mining site.The test results show that the use of low intensity magnetic,high intensity magneticanion reverse flotation process can obtain a good separation index of concentrate iron grade of 68.55%,concentrate yield rate of 36.41%,metal recovery rate of 79.92%,and tailings grade of 9.86%.The selectivity of the ore is good,which provides a reliable technical basis for the rational development and utilization of the ore.
