| Abstract: |
| The development and industrialization of ammonia heap leaching process on low grade oxidized copper ore with high calcium and magnesium content were summarized. The process is of a significant cost advantage compared with the mature stirring ammonia leaching process. The successfully developed ammonia heap leaching-solvent extraction-copper electrowinning industrialization technology provides a feasible choice to treat low grade oxidized copper ore with high calcium and magnesium content. |
