摘　　要：为回收赞比亚某冶炼铜渣中的铜,在工艺矿物学研究的基础上,探索铜渣的选矿工艺。原矿磨矿细度-74μm占85%,一次粗选、三次扫选、两次精选闭路浮选,获得铜品位25.64%、回收率70.74%的合格铜精矿。The mineral processing technology of copper slag is researched for copper recovery from the slag of a copper smelting plant in Zambia based on the mineralogy investigation. While the ore grinding fineness-74 μm accounted for 85%,the qualified copper concentrate with grade of 25. 64%,recovery rate of 70. 74% is obtained by the closed-circuit with one roughing,three scavenging and two concentrate flotation.
