摘　　要：云南某氧化铁矿石铁品位为42.26%,主要铁矿物为赤铁矿,杂质硫含量较高,为1.96%,矿样中的硫主要以硫酸盐的形式存在,与钡生成重晶石。为了充分利用该矿产资源,针对该矿硫含量高的问题,进行了选矿脱硫试验。结果表明通过1粗2精反浮选流程分选,可获得含硫0.14%,含铁52.78%的铁精矿,硫脱出率为92.86%,脱硫效果较好,为该矿通过选矿方法脱硫提供了技术依据。The main iron mineral of an iron oxide ore in Yunnan is hematite,the grade of iron is 42.26%,but the content of impurity S is higher,that is 1.96%.The sulfur in the ore is mainly in the form of sulfate,which forms barite with barium.In order to make full use of mineral resources,aiming at the problem of high sulfur content in the ore,the experimental study on desulfurization by mineral processing was carried out.The experimental results show that the iron concentrate containing 0.14%S and 52.78%Fe can be obtained by reverse flotation with one roughing and two cleaning,and the recovery of S is 92.86%.The desulfurization effect is better.It provides a technical basis for desulfurization of the ore by mineral processing.
