摘　　要：通过岩矿鉴定,扫描电镜,X射线能谱分析等手段,对贵州老文溪重晶石矿进行了工艺矿物学研究,详细研究了样品的物质组成,工艺粒度和主要元素赋存状态,结果表明样品中重晶石含量为66.9%,主要杂质矿物为石英,方解石和白云石。由于重晶石和方解石等矿物紧密交织,且本身硬度较低,容易泥化,建议采用正浮选工艺,分别石英,方解石和白云石进行抑制,从而提高钡的回收率。By means of rock and mineral identification, scanning electron microscopy and X-ray energy spectrum analysis, the process mineralogy of Laowenxi barite ore in Guizhou Province was studied in detail, including material composition, technological particle size and occurrence state of main elements. The results showed that the content of barite in the sample was 66.9%, and the main impurity minerals were quartz, calcite and dolomite. Because barite and calcite are closely interwoven and their hardness is low, they are easy to mud. It is suggested to adopt positive flotation process to suppress quartz, calcite and dolomite respectively, so as to improve the recovery of barium.
