摘　　要：随着矿山开采作业的深入,入选矿石性质变化较大,嵩县丰源钼业有限公司采用直径4.3 m浮选柱来强化扫选,以提高扫选回收率。本文介绍了直径4.3 m浮选柱在钼矿扫选作业中的工业试验情况,结果表明,在整个矿浆试验过程中,设备运行良好。液位自动控制可靠,操作方便;浮选柱运行平稳,泡沫层稳定,没有翻花现象;空气分散均匀,分散度高,气泡大小分布合理,其浮选动力学性能满足了大型浮选柱的要求。累计指标富集比在20左右,回收率在22%左右,全厂总回收率提高了1%~3%。With the development of mining operation of mine and the greater changes of selected ore property,in order to increase the recovery rate of scavenge,the flotation column of 4.3m in diameter is adopted by Songxian Fengyuan molybdenum co.,ltd.to strengthen the scavenge.The industrial test about flotation column of 4.3m in diameter in scavenging operation of molybdenum ore is introduced in this paper,the result shows that in the whole test process of ore slurry,the equipment runs well,its automatic control of liquid level is reliable,and its operation is convenient;the flotation column runs steadily,its foam layer is stable because of stable flow of ore slurry;and the air disperses uniform,its dispersion degree is high,and its bubble size distributes reasonably.The dynamics performance of flotation column of 4.3m in diameter meets the demand of large-scale flotation column.The enrichment ratio of accumulated index is around 20,the recovery rate is about 22%,and the total recovery rate of whole plant increased by 1%~3%.
