内蒙古某铜矿现场铜浮选采用一段磨矿,一次粗选、二次扫选、三次精选的工艺流程,铜银精矿含铜 16.05%,含银 788.40g/t,铜回收率 89.19%,银回收率 77.27%.通过工艺矿物学研究和浮选试验研究,确定一段磨矿,二次粗选、二次扫选、一精再磨、三次精选的工艺流程,最终闭路试验可获得铜银精矿含铜 16.51%,铜回收率 90.06%,含银 852.30 g/t,银回收率81.49%,银回收率提高了 4.22%,达到了提高铜银精矿中伴生银回收率的目的,伴生银得到充分综合回收.
Experimental Study on Improving the Recovery Rate of Associated Silver in a Copper Mine in Inner Mongolia
A copper mine in Inner Mongolia adopts a processe of one-stage grinding,one rough selection,two sweeping selections,and three selections.The copper silver concentrate contains 16.05%copper,788.40 g/t silver,and a copper recovery rate of 89.19% and a silver recovery rate of 77.27%.Through the study of process mineralogy and flotation experiments,a process flow of one stage grinding,two stage rough selection,two stage scanning selection,one stage fine grinding,and three stage selection was de-termined.The final closed circuit test can obtain a copper silver concentrate with a copper content of 16.51%,a copper recovery rate of 90.06%,a silver content of 852.30 g/t,a silver recovery rate of 81.49%,and a silver recovery rate of 4.22%,achieving the goal of improving the recovery rate of associated silver in copper silver concentrate,and achieving comprehensive recovery of asso-ciated silver.
