| Abstract: |
| 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 andthe grade of gold can be further improved by shaking table. The gold concentrate with grade of 121.45g/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 operation of roughering, four operation of cleaning and three operation of scavenging. Furthermore, the grade of gold in copper concentrate reaches 10.77g/t, which meets the evaluation standard. |
