摘要: 介绍了钼的特性及铜钼分离技术发展现状,探讨了铜钼分离最佳工艺操作条件。试验结果表明,当选用巯基乙酸作抑铜浮钼分离抑制剂,可以很好地解决钼矿选别作业回收率低的问题。在选定的最优化条件下,经过多次精选后,钼精矿品位最终可稳定在含Mo 50.00%以上,铜钼分离钼的回收率可提高到85.00%。

Abstract: This paper presents the characteristics of molybdenum and the development status of the copper-molybdenum separation technology and also explores the best process condition for the copper-molybdenum separation.The results show that the low recovery problem of molybdenum minerals separation could be resolved when thioglycolic acid was chosen as the separation inhibitors to suppress copper floating molybdenum.The concentration of Mo in the molybdenum could be above 50% steadily,and the recovery of Mo from Cu-Mo separation could be increased to 85% with the optimum conditions after several cleanings.
