甘肃国宝山铷矿石工艺矿物学研究

摘要

为了查明甘肃国宝山铷矿石的工艺矿物学特征，采用化学分析、X 射线衍射、MLA 等手段进行了矿石主要化学成分、矿物组成以及铷的赋存状态研究。结果表明：矿石中的主要矿物为石英、钠长石和钾长石；矿石中铷主要以类质同象的形式存在于钾长石和白云母中，其中钾长石中占69．53％，白云母中占30．47％。%The research was to study rubidium ore's characteristics of process mineralogical in Guo bao mountain,GanSu.In the following research,it used chemical analysis,X-ray diffraction and MLA method to investigate the mutielement contents,mineral composition and occurrence states of the rubidi-um.The results show that the main minerals in the ore are quartz,albite and feldspar.Moreover,with the analyze of the elements K-feldspar and muscovite,isomorphism was found in the main distribution of Rubidium,while K-feldspar had 69.53 percent and dolomite had 30.47 percent.
