| 摘 要： | 介绍了石煤提钒传统工艺的改进以及酸法-萃取、无盐焙烧-酸浸-萃取、氧化焙烧-碱浸等几种从石煤无污染提取五氧化二钒的工艺流程，上述工艺不但生产过程无环境污染，钒的回收率还大有提高，是很有前途的清洁生产工艺。同时对近两年国际钒价暴涨暴跌的原因进行了探讨，在分析国内主要钒生产厂家的扩产情况下，指出今后儿年五氧化二钒价格有望保持在7万元／t以上。

| Abstract: | This paper introduced the improves of roasting-sodium processing and such pollution-free processing as acid leaching-extration, roasting in air-acid leaching-extration, liming roasting-alkali leaching on extraction of V2O5 from stone coal, the total recovery rate obtains enhances, the industrial application prospect is good. The reason of international V2O5 price rose suddenly and fell suddenly is discussed, the increases production of the main production enterprise were analyzed, then pointed out from now on several years V2O5 prices hopefully up to 70,000 Yuan/tons. |
