| Abstract: |
| Copper-bearing low grade molybdenum concentrate was treated by a series of processes including roasting, two stage ammonia leaching, extraction, stripping, copper electrowinning, and molybdenum precipitation with nitric acid. The final products are cathode copper and ammonium molybdate. The results show that copper recovery rate is 95% above, molybdenum recovery rate is 93% above, and all produces reach first grade of national standard. |
