摘　　要：利用矿相显微镜、X射线荧光光谱分析(XRF)、扫描电子显微镜(SEM)、X射线能谱探针(EDS)等手段对贵州某铅锌矿的工艺矿物学特征进行了研究。原矿化学分析结果显示,矿石中可供选矿回收的主要元素为铅、锌、硫,其品位分别为2.767%、7.818%及18.276%。岩矿鉴定结果表明,主要的金属矿物为黄铁矿、方铅矿及闪锌矿,其矿物含量分别为25.88%、3.18%及11.70%。矿物嵌布粒度特征表明金属矿物中黄铁矿粒径较大,闪锌矿次之,方铅矿最小。黄铁矿、闪锌矿及方铅矿三者常紧密连生,且小部分方铅矿呈稀疏浸染状构造分布于方解石中。元素平衡配分结果表明,铅元素和锌元素的平衡系数分别达99.31%和98.93%,基本查明了该试验矿石中铅元素和锌元素的赋存规律。The process mineralogy characteristics of a lead-zinc mine in Guizhou were studied by means of mineral phase microscope,X-ray fluorescence spectrometry(XRF),SEM and EDS.The chemical analysis results of the crude ore show that the main elements in the ore that can be beneficiated and recovered are lead,zinc and sulfur,with grade of 2.767%,7.818% and 18.276% respectively.Rock ore identification results show that the main metal minerals are pyrite,galena and sphalerite,with mineral contents of 25.88%,3.18% and 11.70% respectively.The grain size characteristics of mineral dissemination indicate that pyrite in metal minerals has a larger grain size,followed by sphalerite and galena.Pyrite,sphalerite and galena are often closely linked,and a small part of galena is distributed in calcite in a sparse disseminated structure.The results of element equilibrium distribution showed that the equilibrium coefficients of lead and zinc reached 99.31% and 98.93% respectively,and the occurrence regularity of lead and zinc in the test ore was basically found out.
