摘要
针对某复杂铜硫铁矿石进行了选矿工艺研究。依据矿石性质,用石灰和CTP作铜硫分离中黄铁矿的抑制剂、Z-200作黄铜矿的捕收剂、111#作起泡剂,采用"铜硫混浮—铜硫分离—磁选"流程,在原矿Cu品位0.59%、S品位7.08%、Fe品位40.31%的条件下,得到了Cu品位19.46%、回收率88.02%的铜精矿,S品位50.71%、回收率81.89%的硫精矿以及Fe品位65.35%、回收率83.69%的铁精矿。所推荐的工艺流程简单,达到了综合回收铜、硫、铁矿物的目的,易于产业化。
The mineral processing technology for a complex Cu - S - Fe ore was studied in this paper. In light of the characteristics of the ore, a flowsheet including Cu - S bulk flotation, Cu - S separation and magnetic separation was introduced, using lime and CTP as the depressant of pyrite in Cu -S separation, Z -200 as the collector of chalcopyrite and 111 # as the frother. The results showed that for the run - of - mine with Cu grade of 0.59%, S 7.08% and Fe 40.31%, Cu concentrate with Cu grade of 19.46% and recovery of 88.02% , S concentrate with S grade of 50.71% and recovery of 81.89% and Fe concentrate with Fe grade of 65.35% and recovery of 83.69% were obtained respectively. The simple flowsheet recommended in this paper could achieve the comprehensive recovery of Cu, S, Fe minerals, and was easy to be industrialized.
