摘　　要：针对氧化铅锌矿高泥、高氧化率、氧化铁矿物严重浸染铅锌矿物、性脆-易于泥化的白云石和方解石含量高等问题,研究从碳酸盐高效脉石抑制剂、胺类捕收剂研制和选矿工艺流程科学设计等方面出发,成功解决了高泥高氧化率氧化铅锌矿与易泥化脉石分离的技术难题,实现了氧化铅锌矿物的有效回收。In view of the problems of high mud and high oxidation rate of lead-zinc oxide ore,serious leaching of lead zinc minerals byiron oxide minerals,brittle dolomite and calcite which was prone to slime.The technical problems separation of lead-zinc oxide ore with high mud and high oxidation rate from easy-muddy gangue were sucessfully solved from the aspects of carbonate high-effciency gangue inhibitor,amine collector development and scientific design of beneficiation process flow,and the effective recovery of lead-zinc oxide ore is realized.
