Progress of the Research on Extraction of Vanadium Pentoxide from Stone Coal and the Market of the V_2O_5

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 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.
