【摘要】 针对云南某低品位铜矿铜浮选指标不太理想，铜精矿中伴生银品位达不到计价要求的现状，对现场生产工艺和生产条件参数进行优化，并进行了分支串流浮选新工艺的试验研究。结果表明，分支串流浮选新工艺是处理该铜矿最佳的浮选工艺，经过闭路试验，可以获得铜精矿铜品位21.33%,含金3.04 g/t,含银23.80 g/t,铜回收率达到92.79%,金回收率为64.51%,银回收率为52.55%的优良指标。与现场生产工艺相比，大幅提高了浮选指标，并且使铜精矿中伴生银品位达到了计价要求，实现了该矿石中铜及伴生金银的高效综合回收。更多还原

【Abstract】 The copper flotation indexes of a low-grade copper ore in Yunnan were not ideal, and the grade of associated silver in copper concentrate could not meet the valuation requirements.In view of this situation, the field production process and production condition parameters were optimized, and the experimental study on new branch series-flow flotation process was carried out. The results showed that the new branch series-flow flotation process was the best flotation process for treating the copper ore. Through the closed-circuit tests, the copper concentrate with copper grade of 21.33%,gold grade of 3.04 g/t and silver grade of 23.80 g/t can be obtained, and the recovery of copper, gold and silver could reach 92.79%,64.51% and 52.55%,respectively. Compared with the on-site production process, the flotation indexes were greatly improved, the associated silver grade in the copper concentrate meeted the valuation requirements, and the efficient comprehensive recovery of copper and associated gold and silver in the ore was realized.更多还原
