摘要： 吉林某低品位高含泥钼矿石中辉钼矿嵌布粒度粗细不均，形态复杂。为确定矿石的高效、低成本开发利用工艺，进行了选矿试验研究。结果表明，Mo 品位为0.081%的矿石在磨矿细度为-74 μm 占55% 的情况下，采用1 粗1 精2 扫、中矿顺序返回流程处理，可获得Mo 品位为 6.955%、回收率为91.83% 的粗精矿；Mo 品位为6.90%、含铜1.12% 的粗精矿在再磨细度为-38 μm 占90%的情况下，采用1 粗5 精2 扫、中矿顺序返回流程处理，可获得Mo 品位53.79%、含铜0.17%、钼作业回收率94.44%的钼精矿。试验流程简洁、高效，可作为开发利用依据。

Abstract: The disseminated grain size of molybdenite in a low-grade and high mud bearing molybdenum ore in Jilin is uneven and the shape is complex. In order to determine the high efficiency and low cost development and utilization process of ore，beneficiation tests were carried out. The results showed coarse concentrate with Mo grade of 6.955% and recovery rate of 91.83% can be obtained by adopting the process of one roughing，one cleaning，two scavenging and the middling returning in sequence when the grinding fineness of the ore with Mo grade of 0.081% is -74 μm accounting for 55%. Molybdenum concentrate with Mo grade of 53.79%，Cu content of 0.17% and molybdenum recovery rate of 94.44% can be obtained by adopting the process of one coarse，five cleaning，two scavenging and middling return in sequence when the regrinding fineness of the coarse concentrate with Mo grade of 6.90% and Cu content of 1.12% is -38 μm accounting for 90%. The test process is simple and efficient，which can be used as a basis for development and utilization.
