某混合硫化矿综合回收试验研究

摘要

The mixed sulfide ore in a tungsten ore of Jiangxi was obtained by using gravity separation-flotation process, which has many sorts of available mineral for comprehensive recovery, containing Cu 8.15%, Bi 0.98%, WO3 2.48%and S 2.48%. This paper presents a new technology of combined flotation-gravity separation processing. The results show the experiment has realized the expected targets of recovering the useful minerals out of mixed sulfide ore, which provides the technical support for the comprehensive resource utilization.%江西某钨矿采用重选-浮选工艺获得的混合硫化矿中，含8.15%Cu、0.98%Bi、2.48%WO3、29.61%S，可回收的有价矿物种类较多。对该矿样本试验采用浮选-重选联合选矿新工艺，全流程试验获得铜精矿品位Cu 22.37%、回收率95.05%，钨精矿品位WO341.19%、回收率65.88%，铋精矿品位Bi 16.88%、回收率65.59%，硫精矿含S 40.23%，其中银主要在铋精矿和硫精矿中富集，其含量分别为4816.0 g/t、512.0 g/t的技术指标，达到了混合硫化矿综合回收多种有用矿物的目的，为该钨矿和其他同类混合硫化矿的资源综合利用提供了技术支撑。
