摘　　要：内蒙古某高硫铜铅锌多金属矿矿石性质复杂,金属矿物之间共生密切。按探索试验确定的铜铅混合浮选—铜铅分离—抑硫浮锌流程进行了选矿工艺技术条件研究。结果表明,采用1粗4精1扫铜铅混浮、1粗1精1扫铜铅分离、1粗4精1扫抑硫选锌、中矿顺序返回闭路流程处理,可以获得优质铜精矿、铅精矿、锌精矿、硫精矿,且产品中其他杂质元素含量均较低,达到了铜、铅、锌、硫分离效果。The properties of Cu-Pb-Zn polymetallic ore with high sulfur from Inner Mongolia are complex,in which metal minerals are associated with each other closely.The study on mineral processing techniques was conducted by the flowsheets of Cu-Pb bulk flotation-separation of Cu amd Pb-sulfur depression Znic flotation.The results show that Cu-Pb bulk flotation with once roughing flotation,four times cleaning flotation and once scavenging flotation,Cu-Pb separation with once roughing flotation,once cleaning flotation and once scavenging flotation,and the flowsheets of sulfur depression and Zn flotation with once roughing flotation,four times cleaning flotation and once scavenging flotation,middlings urderly returm,can obtain the high quality productions as Cu concentrate,Pb concentrate,Zn concentrate and sulfur concentrate,in which contents of impurity elements are low.
