摘　　要：以陕西商洛县楼房沟地区石煤为研究对象,采用化学分析、X射线衍射分析、物相分析,结合先进的MLA在线检测手段,对其进行了详细的工艺矿物学研究,查明钒的赋存状态及主要矿物的嵌布特征。结果表明石煤中的钒绝大部分呈类质同象形式分布于钒云母和白云母中,极少量的钒分布在钒铁氧化物、钒钛氧化物和钙钒石榴子石中。仅有少量钒云母形式存在的含钒矿物钒品位高,结晶较好,结晶粒度较粗,大部分的含钒矿物嵌布粒度微细,给选矿带来较大的难度。In this research, stone coal deposit in Loufanggou area, Shangluo City, Shanxi Province, China was studied by using chemical analysis, X-ray diffraction, phase analysis, as well as MLA analysis in order to find out the occurrence of vanadium in the stone coal. Results show that most of vanadium exists in roscoelite and muscovite in forms of isomorphism, and small amount of vanadium exists in V-Fe oxide mineral, V-Ti oxide mineral and garnet. There are only a small amount of roscoelite with high vanadium grade and bigger grain size, while most of vanadium minerals exist in very small size, which is difficult for recovery by flotation.
