某微细嵌布铜矿的选矿试验研究

针对陕西某微细粒嵌布铜矿的矿石性质,进行了磨矿细度、捕收剂、调整剂、浮选精矿再磨等研究.结果表明:采用磨矿-优先选铜-铜粗精矿再磨-铜精选-铜扫选尾矿选硫工艺,可获得铜精矿品位Cu16.94％,铜回收率80.89％；硫精矿品位S 36.77％,硫回收率78.85％的选别指标.

Experimental Research on Mineral Processing for a Fine Dissemination Copper Ore

Directed at the ore properties of a fine dissemination copper ore in Shanxi,such factors as grinding fineness,collector,modifier and concentrate regrinding were studied.The results show when the technology of grinding—selective copper flotation—copper concentrate regrinding—copper cleaning separation—sulphur flotation from copper tailings was adopted,a copper concentrate of 16.94% Cu with the recovery of 80.89% and a sulphur concentrate of 36.77%S with the recovery of 78.85% were obtained.
