摘要
采用重—浮联合流程回收某低品位铜矿石中的铜和金。金的回收通过重选富集,进一步上摇床提高金的品位,得到的金精矿的品位为121.45 g/t,回收率为60.73%。铜的回收采用氧硫混浮,浮选通过一次粗选、四次精选、三次扫选,得到最终铜精矿的品位为12.56%,回收率为80.49%。且铜精矿中金的品位也有10.77g/t,产品达到计价标准。
The gravity—flotation joint process is adopted for recovering the copper and gold from a low-grade copper ore.The recovery of gold is enriched through the gravity separation and the grade of gold can be further improved by shaking table.The gold concentrate with grade of 121.45 g/t and recovery of 60.73% are obtained.Oxygen sulfur mixing flotation process is adopted for recovering the copper and the final copper concentrate with grade of 12.56% and recovery of 80.49% is obtained through one stage roughering,four stages of cleaning and three stages of scavenging.Furthermore,the grade of gold in copper concentrate reaches 10.77 g/t,which meets the valuation standard.
