| 摘 要： | 在工艺矿物学研究的基础上,对含铜矿物较多、嵌布粒度粗细不均匀、且可浮性相差悬殊的铜锡硫化矿进行了选矿试验研究。在使用较高选择性药剂条件和最优的药剂制度下,采用半优先浮铜—铜与砷硫分离—硫化物再选铜的选矿工艺流程,实现了铜的较好回收及铜砷分离,最终获得了含铜18.32%、回收率82.44%、含砷0.719%的铜精矿。试验结果达到了预期目的。

| Abstract: | Based on process mineralogy, dressing experiments on copper-tin symbiotic copper concentrate was carried out. This copper concentrator has inhomogeneous particle size, many copper minerals and great difference on floatability. Separation of copper and arsenic was achieved by the process, semiselective copper flotation -separation of copper and arsenic-copper reconcentration from sulfur concentrate, by selective reagent under the best reagent system. The recovery of copper is 82.44% and the content of copper concentrate containing 0.719% arsenic is 18.32%. |

| Keywords: | semiselective copper flotation reconcentration of sulfur concentrate separation of copper and arsenic |
