某难选金矿石浮选工艺试验研究

Research on recovering gold from the refractory gold ore

根据矿石性质及生产实际情况,试验从常规浮选、抑碳浮选和粗精矿再磨浮选三个方面进行了研究,为现场生产改造推荐了试验指标较好的粗精矿再磨浮选工艺。

According the properties of the refractory gold and operating condition of the plant, Conventional flotation, such as depressing carbon flotation and regrinding primary concentrate flotation were researched. The study put up the process of flotation after regrinding primary concentrate for operation . The application of the reformed process demonstrated that the operating yields are favorable making better economic gains for the gold mine.
