摘　　要：本文针对细粒浮选尾矿品位偏高的问题,通过收集细粒浮选尾矿品位数据,分析指标的变化趋势、均值以及波动,最终通过改变浮选原矿粒级含量、优化浮选操作、确定最优药剂制度,减轻它们对浮选选别效果的影响,降低浮选尾矿品位,提高浮选作业回收率,增产创效。Aiming at the problem of high fine-grained flotation tailings grade,this paper collects fine-grained flotation tailings grade data,analyzes the trend,average and fluctuation of indicators,and finally optimizes flotation by changing the flotation raw ore size content Operate and determine the optimal reagent system to reduce their impact on the flotation effect,reduce the grade of flotation tailings,increase the recovery rate of flotation operations,and increase production and efficiency.
