我国钒矿资源,尤其是石煤资源储量丰富。统计表明:我国钒矿资源保有储量(以V2O5计)约3400万t,累计查明资源储量约3600万t,主要分布在四川、陕西、湖南、安徽、湖北等地,5省合计储量占全国的90.1%,累计查明储量占全国的88.9%。含钒石煤是我国一种独特的钒矿资源,其中V2O5储量约1128万t,占钒矿资源总储量的37.0%,主要分布在湖南、湖北、浙江、贵州等地,其中有工业开采价值的(w(V2O5)>0.8%)石煤中钒储量占62.6%。含钒石煤是我国钒矿资源利用的一个重要发展方向,本文综述了火法-湿法联用、湿法从石煤中提取钒的工艺以及存在的问题,对生物浸出钒及其它有价金属前景进行了展望。
Abstract：The reserves of vanadium resources,especially stone coal resources are abundant in China.Based on the statistical data,the available reserves of vanadium pentoxide resources are about 34 million tons,while accumulative total reserves are about 36 million tons,which are mainly distributed in provinces of Sichuan,Shanxi,Hu'nan,Anhui and Hubei.The available reserves and accumulative total proven reserves in above provinces account for 90.1% and 88.9% of the whole reserves in China,respectively.The stone coal is a special vanadium ore in China which reserves of V2O5 are about 11 million tons and account for 37.0% of the whole stone coal vanadium reserves,which are mainly distributed in provinces of Hu'nan,Hubei,Zhejiang and Guizhou.The available vanadium reserves in stone coal account for 62.6% which have industrial prospect and the content of V2O5 in these stone coal is more than 0.8%.Finally,main vanadium extraction processes by pydro-hydrometallurgy and hydrometallurgy are reviewed and some problems are also discussed.A novel technology,bioleaching,used in leaching of vanadium and other valuable metals from stone coal is prospected.
