| Abstract: |
| The Cu-Zn separation technology is key to recovery the associated metalssuch as copper, zinc and so on from pyrite comprehensively. The selective flotationflowsheet is adopted based on the characteristics of the ore in which the content of sulphur is high, the content of copper and zinc is low and the intergrowth is dense. Thistechnological flowsheet realized successfully the separation of the copper and zinc in theneutral medium adopting the sodium sulphide combination depressant, and achieved threequalified products : copper concentrate, zinc concentrate and sulphur concentrate and alsorealizing successfully the comprehensive utilization of ore resource. |
