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。

Abstract: 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.

Key words: Gold ore slime, Cyclonic-static micro-bubble flotation column, Semi-industrial test
