摘　　要：湖北通山某含钒石煤矿中钒的主要载体矿物为云母和碳质物，未发现钒的独立矿物，钒是以类质同象和离子吸附形式存在于这些矿物中。钒的价态分析表明，石煤中的钒主要以三价形式存在，少量以四价和五价形式存在。经扫描电镜和能谱微区成分分析，钒主要与以云母为主的载体矿物同步出现，云母中V：0，的含量不均匀，一般在1．00％-4．50％之间。The process mineralogy characteristics of stone coal containing vanadium in Tongshan, Hubei have been studied in this paper. There are no independent mineral of vanadium in the ore. The main carrier mineral of vanadium are mica and carbonaceous material , in which the vanadium exists in the form of isomorphou and ion adsorption. The valence analysis showed that, the vanadi- um in the stone coal mainly exists in the form of trivalent, and a small amount in the form of tet- ravalence and pentavalence. Acording to the scanning electron microscopy and energy spectrum micro area composition analysis, most vanadium is accompanied by the mica - based carrier minerals. The content of V2O5 in mica is uneven, generally in the range of 1.00 to 4.50%.
