摘　　要：某铜钼矿磨矿细度较粗,应用柱机联合工艺,采用两次粗选(一粗浮选柱、二粗浮选机)、一次精选(浮选柱)、一次扫选(浮选机)流程,最终得到Cu品位17.24%、Mo品位3.18%的铜钼混合精矿,Cu、Mo回收率分别为92.71%和85.96%。在现场实际应用中,相对前期单一浮选机工艺而言,改造后采用柱机联合工艺Cu、Mo回收率分别提高0.99%和3.52%,且利用浮选柱高富集比原理,将精选次数由原来的两次精选缩短为一次精选,简化了现场工艺流程。The grinding fineness of a copper and molybdenum ore is coarse,and the combined process of column machine is applied.The process of two rough separation(one rough flotation column,two rough flotation separator),one purification(flotation column)and one sweep separation(flotation machine)are adopted.Finally,the Cu and molybdenum mixed concentrate with Cu grade of 17.24%and Mo grade of 3.18%is obtained.The recoveries of Cu and Mo were 92.71%and 85.96%,respectively.In the field application,compared with the previous single flotation machine process,the Cu and Mo recovery rates increased by 0.99%and 3.52%,respectively,and the flotation column high enrichment ratio principle was used to shorten the selection times from the original two selections to one selection,simplifying the field process.
