介绍了从石煤中提取V_2O_5的焙烧钠化工艺的改进以及酸浸-萃取、空气焙烧-酸浸-萃取、石灰焙烧-碱浸等无污染工艺，总回收率得到提高，工业应用前景良好。讨论了国际V_2O_5价格暴涨暴跌的原因。分析了主要生产企业的增产情况，指出今后几年V_2O_5价格有望回升到7万元/t。
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 V_2O_5 from stone coal,the total recovery rate obtains enhances,the industrial application prospect is good.The reason of international V_2O_5 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 V_2O_5 prices hopefully up to 70,000 Yuan/tons.
