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.
