摘　　要：某浮选厂回采处理的高氧化低品位尾渣性质复杂,原矿金品位0.9 g/t,矿石氧化率75%~80%,泥质含量较重,浮选回收难度较大,精矿品位与回收率指标双双偏低。为了使金精矿品位及回收率得到较大地提高,实现效益增收,开展了新型高效活化剂探索试验研究工作,试验表明新型高效活化剂能高效抑制矿泥,活化金矿物,在浮选精选生产实际流程中添加适量的新型高效活化剂,金精矿品位与回收率得到了有效提升,取得了可观的经济效益。The properties of the high-oxidation,low-grade tailings processed by a flotation plant are extremely complex.The original ore has a gold grade of 0.9 g/t,an oxidation rate of 75%to 80%,and contains a significant proportion of clay,making flotation recovery challenging,resulting in both concentrate grade and recovery rate being subpar.In order to substantially improve the concentrate grade and recovery rate of gold,thereby achieving increased economic benefits,an experiment on novel high-efficiency activators was conducted.The results demonstrated that the new high-efficiency activator could effectively suppress slimes and activate gold minerals.By adding an appropriate amount of this new activator in the actual flotation concentration process,the grade and recovery rate of the gold concentrate were effectively improved,yielding considerable economic benefits.
