摘要
江西某硫化铜矿矿石性质复杂,铜氧化程度较高.在工艺矿物学研究的基础上,确定了"铜硫混浮-混合精矿再磨-铜硫分离浮选"试验流程,并使用了新型药剂WH-1#活化铜、组合药剂白1、白2(1∶1)抑制硫,成功地实现了低碱条件下的铜硫分离,最终获得了品位为20.23%、回收率为85.76%的铜精矿及品位为39.19%、回收率为65.68%的硫精矿.
The ore property of a copper.sulfide ore in Jiangxi is complicated with high degree copper oxida- tion. The flotation sheet of "Cu-S bulk flotation + mixed concentrate regrinding + Cu-S separation flotation" is deternfined based on mineralogical analysis. WH-1 agent is used to activate copper while the combination agents whitel and white2(l:l) to inhibit sulfur. The copper and sulfur are flotated under low alkalinity conibn. The grade of copper concentrate reaches 20.23 % with recovery rate of 85.76 %. The grade of sulfur concen- trate attains 39.19 % with recovery rate of 65.68 %.
