摘要:

某金矿石中金矿物的嵌布粒度细且产出特征复杂,除与黄铁矿、毒砂共生关系密切外,与脉石矿物嵌布关系也较为密切。针对该矿石性质,进行了浮选工艺研究,确定了最佳工艺参数和工艺流程。结果表明:在一段磨矿细度-0.045 mm占50 %时,采用两段磨矿两段选别—中矿再磨工艺流程,闭路试验可获得金精矿金品位35.66 g/t、金回收率90.02 %,尾矿金品位0.38 g/t的较好指标。

Abstract:

The gold minerals in a gold ore have fine disseminated grain size and complex occurrence characteristics.In addition to the symbiotic relationship with pyrite and arsenopyrite,they are also closely related to the dissemination of gangue minerals.Based on the property of the ores,the flotation process was studied and the optimal process parameters and process flow were determined.The results show that when the one-stage grinding fineness of -0.045 mm accounted for 50 %,and the closed-circuit test on two-stage grinding two-stage separation-middling regrinding process was carried out,good indexes were obtained,for example,the gold grade in the gold concentrates is 35.66 g/t,the gold recovery rate is 90.02 %,and the gold grade in the tailings is 0.38 g/t.
