    南秦岭商南县湘河钒矿钒的赋存状态研究

    The occurrence state of vanadium in Xianghe Vanadium deposit, Shangnan County, Southern Qinling

    • 摘要: 湘河钒矿属黑色岩系变质沉积型钒矿,赋矿层位为寒武系下统水沟口组,赋矿岩性为构造破碎重晶石化硅化泥硅质板岩和炭硅质板岩。本次工作通过扫描电镜SEM/EDXS X衍射面扫描、电子探针能谱分析、物相分析等研究,认为该地区,钒主要与水白云母关系密切,其次是高岭石、胶状褐铁矿、金红石等,与石英、重晶石、钾长石、白云石、黄铁矿等关系不密切。钒没有独立矿物,云母类中的V2O5占有率为64.68%,氧化铁及粘土矿物中的V2O5占有率为32.34%,难溶矿物中的V2O5占有率为2.98%。对该矿床钒元素赋存状态的研究,为研究同类型钒矿床的成因及改进选矿工艺提供了依据支持。

       

      Abstract: Xianghe vanadium deposit belongs to metamorphic sedimentary vanadium deposit occurring in black rock series of the Lower Cambrian Shuigou Formation, in which the host lithology is tectonically fractured-barite silicifiedargillaceous siliceous slate and carbonaceous siliceous slate. Through SEM SEM/EDXS X diffraction surface scanning,electron probe energy spectroscopy analysis and phase analysis, it is believed that vanadium is mainly closely related to omite, followed by kaolinite, gelatate limonite, rutile, and not closely related to quartz, barite, potassium feldspar, dolite and pyrite. Vanadium has no independent minerals, V2O5 in mica is 64.68%, V2O5 in iron oxide and clay minerals 32.34%,and V2O5 in refractory minerals 2.98%. The study on the occurrence state of vanadium elements in this deposit provides a support for studying the origin of similar vanadium deposits and improving the beneficiation process.
