摘　　要：介绍了山东某金矿的原矿性质及洗矿矿泥中金的分布特点,对金在微细粒级明显富集的矿泥,应用旋流-静态微泡浮选柱组成的1粗1精闭路浮选半工业试验系统进行了矿泥分选研究,并在最佳工艺技术参数条件下进行了系统的稳定性研究,对平均金品位为2.21 g/t的矿泥,获得了平均金品位为98.98 g/t、回收率为88.15%的金精矿。试验指标明显优于用浮选机组成的分选系统的指标,表明旋流-静态微泡浮选柱对细粒及微细粒物料的分选具有显著的优越性。Gold ore properties and gold distribution characteristics in some gold ore slime by washing the crushed in Shandong Province were introduced. The slime in which gold is significantly concentrated in micro-fine particles was processed with one stage scavenging and one stage cleaning semi-industrial test system with cyclonic-static micro-bubble flotation column, and stability of the system research was carried out, which obtained an average gold grade of 98.98 g/t, recovery of 88.15% of the gold concentrate ,on the average gold grade of 2. 21 g/t of slime. The result was obviously better than the index of floatation machine production, which showing cyclonic-static micro-bubble flotation column has significant advantages in fine particles and micro-fine particles separation.
