Selective reduction of cupriferous calcine |
| 摘要 |
A process for selectively reducing calcine from a copper/nickel containing sulfidic material includes subjecting the calcine to a mildly reducing atmosphere at relative high temperatures. CuO is selectively converted to Cu<SUB>2</SUB>O which can easily be separated by leaching from other metals which may be present in the material.
