摘要
通过详细的化学分析,矿相显微镜镜下鉴定的方法对钼矿石进行系统的工艺矿物学研究,查明该矿石中的矿物组成、辉钼矿的嵌布特性、粒度特征、不同筛级中的解离度、表面性质的变化、辉钼矿和辉钼矿集合体中钼及其他杂质元素的组成和含量等,再经过充分的分析论证,分析出矿石难分难选的几个主要矿物学因素,辉钼矿的粒度极细小和与脉石矿物之间的密切嵌布关系等是最主要的难选因素。
Mineralogical study on the refractory molybdenum ore from Mongolia is carried out by multiple methods of chemical analysis, mineral samples on microscopic characterization and electro--microscopic scan for different minerals, the features of molybdenum ore has been determined, such as ore composition, grain size, the embedded features of molybdenite, dissociation characteristics on separation, surface proper- ties. The composition of molybdenum and other impurity elements in molybdenite components and molyb- denite collections are also determined. At the end, the main mineralogical factors of refractory molybde- num ore could be given to interpret our acquired results.
