摘要: 在对云南某含铜0.16%、铅0.86%、锌2.92%的多金属硫化矿矿样进行简单的工艺矿物学研究的基础上,着重对矿石中有价组分回收的工艺技术条件进行了研究,采用1粗3精2扫铜铅混浮,1粗2精1扫选铜、1粗2精1扫选铅铜铅分离,1粗4精2扫选锌的闭路试验流程处理该矿样,最终可获得铜、铅、锌3种精矿产品,铜、铅、锌品位分别为22.17%、52.19%、39.15%,回收率分别为75.65%、84.25%、44.63%。

Abstract: Based on the simple process mineralogical studies on a polymetallic sulfide ore with copper of 0.16%,lead of 0.86%,zinc of 2.92%,the technical conditions for recovering the valuable components are emphasized.The closed-circuit test process of copper-lead bulk flotation by one-roughing,three-cleaning and two scavenging,copper concentration by one-roughing,two-cleaning,and one-scavenging,lead concentration by one-roughing,two-cleaning,and one-scavenging,and zinc separation by one-roughing,four-cleaning and two scavenging is carried out.Finally,three concentrates of copper,lead and zinc with Cu grade of 22.17%,Pb grade of 52.19%,Zn grade of 39.15% at a recovery of 75.65%,84.25%,44.63% respectively are obtained.
