摘　　要：为使金属钼能从钼含量为1.62%的铜钼多金属硫化矿混合精矿中高效分离,探索了一种加温预处理-浮选分离的工艺。混合精矿首先经加温脱药,脱药温度为90℃,加温时间为2.5 h,在不磨矿的情况下直接进行一粗-四精-一扫的钼浮选分离工艺,并配合专门浮钼的选择性捕收剂MY,获得了钼品位为45.24%,回收率为86.88%的钼精矿,并使铜、铋等其他有价金属元素富集至浮钼尾矿中,有效的解决了钼从铜钼多金属硫化混合精矿中难分离的问题。In order to separate molybdenum from copper-molybdenum polymetallic sulfide concentrate with 1.62% Mo,the heating de-reagent-flotation process was explored.Through the process of heating de-reagent with the temperature of 90℃ and time of 2.5 hours and one roughing,four cleanings and one scavenging closed-circuit flotation process with the selective collector of MY,the Mo concentrate with 45.24% molybdenum and recovery of 86.88% was obtained,and other valuable metallic elements such as copper and bismuth were enriched into Mo tailings.The problem of difficult separation of molybdenum from copper-molybdenum polymetallic sulfide concentrate was solved effectively.
