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 %.
