以往我厂在处理原生铜锌硫矿石时,在优先选铜过程中,一直采用氰化钠和硫酸锌抑制闪锌矿和黄铁矿分选铜的工艺。在无产阶级文化大革命凯歌声中,1971年10月开始了新工艺的工业试验,在广大工人、技术人员和领导干部的共同努力下,克服种种困难,终于在优先选铜工艺中,逐步取消了氰化钠、硫酸锌,实现了无抑制剂分选铜锌硫的新工艺,并取得了良好效果。四年来的生产实践证明,在处理原生铜锌硫矿石时,只要严格控制pH值为9.5～9.8,适当降低捕收剂用量,掌握好工艺操作,不用氰
In the past I plant in the treatment of primary copper zinc sulfide ore, copper in the preferred process, has been using sodium cyanide and zinc sulfate inhibition of sphalerite and pyrite separation of copper process. In the triumphant proclamation of the Great Proletarian Cultural Revolution, the industrial experiment of new technology was started in October 1971. With the joint efforts of the broad masses of workers, technicians and leading cadres, overcoming all kinds of difficulties was finally canceled in the process of preferential copper selection Sodium cyanide and zinc sulfate. The new technology of copper sulfate zinc sulfur without inhibitor was realized and the good effect was achieved. Four years of production practice has proved that when dealing with the primary copper zinc sulfide ore, as long as the strict control of pH 9.5 ~ 9.8, appropriate to reduce the amount of collector, master the process operation, without cyanide
