通过连续监控矿浆电动势(EMF)的方法,从既含硫化矿物又含氧化矿物的矿浆中回收铜。并且对标准银一氯化银电极而言,只要当矿浆电动势大约超过-30毫伏时,就要向矿浆中连续添加水溶性硫化物,其用量为0.05～7磅(含硫量)/吨。当电动势约小于-30毫伏时则停止添加。之后,在有硫化铜矿物的捕收剂存在下进行浮选,矿石中的绝大部分硫化矿物和大部分的氧化矿物以精矿产出。 Copper is recovered from a slurry containing both sulfide and oxide minerals by continuously monitoring the slurry electromotive force (EMF). And for standard silver silver chloride electrodes, as long as the slurry electromotive force exceeds approximately -30 millivolts, a continuous addition of water-soluble sulfide to the slurry takes 0.05 to 7 pounds (sulfur content) per tonne . When the emf is less than about -30 millivolt, stop adding. Afterwards, flotation was carried out in the presence of a collector of copper sulphide minerals, producing most of the sulphide minerals and most of the oxide minerals in the ore as concentrates.
