坦桑尼亚潘达地区某铌矿工艺矿物学研究

Study on the Process Mineralogy of Niobium in the Colombite Ore in Mpanda,Tanzania

利用光学显微镜、X-射线衍射分析(X-RD)、扫描电镜、矿物自动分析仪(MLA)及EDS能谱分析,结合化学分析等综合手段,从矿石的物质组成、嵌布粒度、共生关系及铌元素的赋存状态等方面,详细论述了该矿石的工艺矿物学特征,为采用合理的选别工艺提供了科学依据。

By means of optical microscope,X-ray diffraction analysis(X-RD),scanning electron microscopy(SEM),mineral automatic analyzer(MLA)and EDS spectrum analysis,combined with the comprehensive methods such as chemical analysis,study in the ore composition,disseminated grain size,paragenetic assemblage of mineral and state of niobium elements,etc.,in detail elaborated the process mineralogy characteristics of the ore,The research could provide reliable reference for the adoption of a reasonable separation process.
