| 摘 要： | 国外某金矿石含金量达7.98 g/t，粒度细小、主要呈浑圆粒状和角粒状的金矿物与主要载金矿物黄铁矿和毒砂嵌布关系密切。为高效开发利用该矿石资源，在探索试验基础上，采用重选-浮选工艺流程进行了选矿试验研究。结果表明，在磨矿细度为-0.074 mm占60%的情况下，采用1粗1精开路摇床重选，重选尾矿1粗2精2扫、中矿顺序返回浮选流程处理，最终可获得金品位为450.00 g/t、回收率为17.48%的重选金精矿和金品位为54.20 g/t、回收率为76.54%的浮选金精矿，总精矿的金品位为64.80 g/t、回收率为94.02%。因此，重浮联合流程是处理该矿石的有效流程。

| Abstract: | A gold ore from a foreign mine contains 7.98 g/t Au，exist in fine，granular and rounded granular gold minerals closely associated with gold-bearing minerals like pyrite and arsenic pyrite.Based on the probe tests，beneficiation research was conducted by applying the process flow-sheet of gravity separation-flotation to realize efficient utilization of the ore.The results indicated that under the proper grinding fineness of 60% -0.074 mm and by an open-circuit separation of a shaking table of one roughing and one cleaning，one roughing，two cleaning and two scavenging，and the middlings returned to the previous operation deal with shaking table tailings，gravity gold concentrate with 450.00 g/t Au and recovery of 17.48% by was obtained，and flotation concentrate containing 54.20 g/t Au and recovery of 76.54% was achieved.Equivalently by the whole process，mixed concentrate will contain 64.80 g/t Au with Au recovery of 94.02%.As can be seen，the combined process of gravity separation-flotation is an appropriate and effective flow-sheet to treat the ore. |
