摘　　要：碳酸盐岩型铅锌矿矿物组成简单,选矿的难点在于矿石呈胶状结构和交代结构,磨矿解离困难,铅锌硫化矿物可浮性多变且彼此交错重叠,加之黄铁矿对方铅矿和闪锌矿分选的干扰,脉石矿物中白云石和方解石易泥化进而恶化分选环境,导致碳酸盐岩型铅锌矿选矿难度较大。综合相关文献,从磨矿流程、选别工艺流程、浮选药剂、选矿设备等方面对碳酸盐岩型铅锌矿选矿技术进行了综述,初步总结分析了碳酸盐岩型铅锌矿矿床特征与选矿技术的内在联系和规律性,可为选矿技术的确定提供一定的指导和参考,对提高资源综合利用率,促进资源优势转变为产业优势,满足经济发展对铅锌资源的日益增长需求具有重要的意义。The mineral composition of carbonate-hosted lead-zinc deposits is simple.But the mineral processing is difficult because its minerals latex like texture and metasomatic texture,changeable and overlapping floatability of lead-zinc sulfide minerals,together with interference of pyrite on galena and sphalerite separation.According to related literature,the mineral processing of carbonate-hosted lead-zinc deposits were reviewed from milling flowsheet,mineral processing flowsheet,flotation reagent,beneficiation equipment and so on.The internal relationship and regularity between deposit characteristics and mineral processing are primarily summarized,which can provide guidance and reference for the determination of mineral processing.It is of great significance to enhance the comprehensive utilization of carbonate-hosted lead-zinc deposits,promote the transformation of resource advantage into industrial advantage,that meet the increasing demand of lead and zinc resources for economic development.
