内蒙古某铷矿工艺矿物学研究

采用化学多元素分析、光学显微镜分析、扫描电镜分析和矿物参数自动分析系统(MLA)等分析手段对内蒙古自治区某铷矿的石化学成分、矿物组成及含量、嵌布特征、粒度分布、铷元素的赋存状态等进行研究。结果表明：矿石中Rb₂O含量为0.107%,铷矿石的主要矿物为钠长石、石英、钾长石、云母、高岭石，铷主要以类质同象的形式存在于云母和钾长石中，云母中含Rb₂O 0.886%,分布率为47.49%,钾长石含Rb₂O 0.226%,分布率为52.51%;矿石中的石英粒度最大，钾长石和钠长石的嵌布粒度较接近，为0.74～1.2 mm,云母粒度主要分布在0.02～0.85 mm,微细粒云母和穿插在长石或被长石包裹中的云母较难实现单体解离，也较易产生泥化，不利于铷的选矿回收。

Process mineralogy of a rubidium mine in Inner Mongolia

A rubidium ore in Inner Mongolia autonomous region as the research object, through the analysis of the chemical element analysis, optical microscope, scanning electron microscopy (sem) analysis and MLA (mineral parameters) automatic analysis system of rubidium ore sample analysis methods such as chemical components, mineral composition and content and characteristics of embedded, particle size distribution, the state of rubidium elements of process mineralogy research.The results show that the main minerals of rubidium ore are Aladdin, quartz, potassium feldspar, mica, kaolinite and so on.The content of Rb2O in the ore is 0.107%, and rubidium mainly exists in mica and potassium feldspar in the form of homogeneity.The rubidium content in mica is 0.886% and the distribution rate is 47.49%.The content of potassium feldspar rubidium is 0.226%, and the distribution rate is 52.51%.Among the ores, quartz has the largest grain size, while potassium feldspar and albite have similar dissemination sizes, ranging from 0.74 mm to 1.2mm.The particle size of mica is mainly between 0.02 and 0.85mm. It is difficult for mica and mica interspersed in feldspar or coated by feldspar to achieve monomer dissociation and easy to produce mud, which is not conducive to the recovery of rubidium in mineral processing.
