摘　　要：本文以内蒙古某高硫铅锌矿浮选尾矿为研究对象,采用X射线衍射仪(XRD)、工艺矿物学自动分析仪(BPMA)对尾矿的矿物组成进行分析,并进行活化浮选综合回收黄铁矿的试验研究。结果表明,以浓硫酸为活化剂,乙基黄药和异戊基黄药为组合捕收剂,采用“一粗一扫两精”的浮选工艺,可获得产率9.31%、硫品位37.78%的精矿产品,精矿中硫的回收率达到77.13%,实现了原浮选尾矿中硫的综合回收利用。Taking the flotation tailings of a high-sulfur lead-zinc mine in Inner Mongolia as the research object,this paper uses X-ray diffraction(XRD)and Bgrimm process mineralogy analyzing(BPMA)to analyze the mineral composition of the tailings,and conducts an experimental study on the comprehensive recovery of pyrite by activation flotation.The results show that using concentrated sulfuric acid as activator,ethyl xanthate and isoamyl xanthate as combined collectors,and the flotation process of "one roughing,one sweeping and two refining",the concentrate product with yield of 9.31%and sulfur grade of 37.78%can be obtained,the recovery rate of sulfur in the concentrate reaches 77.13%,realizing the comprehensive recovery and utilization of sulfur in the original flotation tailings.
