摘　　要：刚果某氧化铜矿石氧化率和结合率高,单一硫化法分选效果不理想。采用组合调整剂和组合捕收剂获得了较好的浮选指标。在铜精矿品位波动不大的情况下,组合药剂的使用能显著提高铜的选矿回收率。铜精矿品位达20.03%,铜回收率达80.79%。The characteristic of a refractory copper oxide ore in Congo is the high oxidation radio and the high combination ratio.It couldn＇t reach ideal target by the process of vulcanization and flotation.A better flotation index was obtained when the combined regulators and combined collectors were used in flotation.The recovery of copper was improved notably using combination reagent under the condition of stable grade of copper concentration.Copper concentrate of Cu 20.03%with a recovery of 80.79% was obtained.
