摘　　要：采用扫描电子显微镜、MLA矿物自动分析仪、X射线衍射分析仪等综合研究了贵州六枝地区黏土型锂矿物的矿物学性质。结果表明:矿石中的主要有价元素为锂,锂含量为0.56%,主要呈微细粒鳞片状集合体,嵌布粒度细微,常呈胶结物包裹伊利石、方解石、石英、黄铁矿等矿物,少数锂绿泥石常呈微细粒鳞片状包裹在方解石和石膏中,可选性差,且多与其他矿物呈紧密连生,难以通过物理选矿方法有效分离。建议对矿石采用煅烧、浸出等冶金方案提取矿石中的锂元素。The mineralogical properties of clay-type lithium minerals in Liuzhi area of Guizhou Province were studied by means of scanning electron microscope,MLA automatic mineral analyzer and X-ray diffraction analyzer.The results show that the main valuable element in the ore is lithium,with a lithium content of 0.56%,which is often in fine-grained scale-like forms aggregate with fine distribution granularity.It is often in the form of cement wrapped in illite,calcite,quartz,pyrite and other minerals.A small number of lithium chlorite is often in fine-grained scale-like forms wrapped in calcite and gypsum,with poor selectivity,and most of them are closely connected with other minerals.It is difficult to effectively separate by physical beneficiation methods.It is suggested to use calcination,leaching and other methods to extract lithium from ore.
