摘　　要：云南大红山某铜铁矿选矿厂以丁基黄药为捕收剂、730A+2~#油为起泡剂浮选铜,不仅药剂用量较大,生产过程不稳定,而且生产指标不理想。试验对新型、高效药剂的浮选效果进行了研究。结果表明:采用现场磨矿细度、浮选浓度及工艺流程,以DF-64+DF-8(质量配合比为1∶2)为捕收剂、DF-K90为起泡剂,获得了铜品位为23.42%,铜回收率为95.39%铜精矿,不仅提高了铜精矿品位2.42个百分点左右、铜回收率2.39个百分点左右,而且稳定了生产过程,降低了药剂用量和药剂成本,经济和社会效益显著。The copper mineral of a certain copper ore dressing plant in Yunnan Dahongshan was recovered by flotationwith butyl xanthate as collector,730A＋2~# oil as frother,of which the process had the disadvantages of large reagents consump-tion,unstable production process and poor production indexes.The flotation performance of the new efficient reagent was inves-tigated.Results indicated that by using the site grinding fineness,flotation concentration and process in production,and with DF-64＋DF-8（The mass ratio 1∶2）as collector,DF-K90 as frother,final copper concentrate with copper grade of 23.42% andrecovery of 95.39% with 2.42 and 2.39 percentage points improved respectively was obtained.The new reagent can stabilizeproduction process,and reduce reagents dosages and cost,with significant economic and social benefit.
