含钒云母工艺矿物学研究

Study on Process Mineralogy of Vanadium-containing Mica

为了更加清楚地认识钒在含钒云母中的赋存状态,为从含钒云母中提钒提供理论指导,采用能谱(EDS)、矿物自动分析(MLA)等方法对含钒云母进行了工艺矿物学研究。研究结果表明,含钒云母中含钒黑云母占94.33%,透辉石占4.61%,此外还含有少量磷灰石、绿泥石、正长石,以及微量的褐铁矿、钙长石、钠长石等矿物;主要赋存元素为氧、镁、铝、硅、钾、钛、钒、铁,其中钒元素全部赋存于黑云母中。

In order to know more about vanadium in vanadium-containing mica,it is necessary to provide theoretical guidance for vanadium from vanadium mica. In this study,EDS and MLA are used to study the mineralogy of vanadium mica. The results show that vanadium mica contains 94. 33% vanadium biotite,diopside accounted for 4. 61%,in addition to a small amount of apatite,chlorite,feldspar,and trace limonite,calcium feldspar,sodium feldspar and other minerals; the main elements are： O,Mg,Al,Si,K,Ti,V,Fe,and vanadium elements all occur in biotite.
