摘　　要：为提高某大型铜钼矿微细粒铜浮选指标,进行了铜浮选药剂和工艺试验研究,考察了捕收剂种类及用量、擦洗及脱泥新工艺对浮选指标的影响。结果表明,在适宜的药剂制度及新工艺条件下,铜浮选闭路试验可获得铜精矿品位23.22%、铜回收率89.10%的较好指标。To improve the copper flotation indices of a large copper⁃molybdenum mine,experimental studies on reagent regime and beneficiation process were carried out,and the influences of collector type and dosage,scrubbing and desliming parameters on flotation indices were investigated.The results of a closed⁃circuit test of copper flotation show that a copper concentrate with Cu grade of 23.22%can be obtained at 89.10%recovery under the optimal reagent system and renewed process conditions.
