摘  要:大平掌铜矿V2矿体低贫铜矿石出矿量逐年增加,企业生产运营成本有增无减。为优化铜浮选指标、增加企业效益,采用分支串流浮选工艺对大平掌硫化铜矿进行试验研究。试验结果表明,新工艺可将入选矿石铜品位从0.51%提高至0.91%,最终获得铜品位23.67%、回收率92.06%的铜精矿,其指标比常规浮选工艺分别高0.84和0.05百分点,且捕收剂总用量降低了1/4,总精选次数减少2次。分支串流浮选工艺提高了入选铜品位,优化了浮选内部流程结构和药剂制度,减少了药剂用量和精选设备,节能增效明显。The operating cost of the company is rising along with the amount of low lean copper ore in the Dapingzhang Copper Mine's V2 orebody.In response,the branch stream flotation process was employed to conduct on the Dapingzhang sulfide copper mine,with the objective of improving the flotation index of copper and increasing the profits of the enterprises.According to the test findings,the copper grade of the feed increased from 0.51%to 0.91%by the novel process,and a copper concentrate with a copper grade of 23.67%and a recovery rate of 92.06%was obtained,which was 0.84 and 0.05 percentage points higher than those of the traditional flotation method.Furthermore,the total dosages of collectors decreased by 1/4 and the total selection times reduced by 2 times.Overall,the branch stream flotation process improved the grade of selected copper,optimized the internal flotation process structure and reagent system,reduced the dosage of reagent and selecting equipments,and resulted in significant energy savings and improved efficiency.
