摘要
介绍了石煤资源的分布情况及工艺现状,分析了各种提钒工艺的优缺点。根据石煤提钒的发展历程及其研究现状,指出石煤提钒工艺的发展趋势呈现出以下特点:①石煤提钒矿石分解优选酸分解工艺;②石煤酸浸液中分离富集钒工艺多元化;③石煤提钒产品多样化;④石煤提钒工艺过程多元素综合回收集约化。
The distribution of stone coal in China was introduced and processes of vanadium extraction from stone coal,including their advantages and disadvantages,were reviewed.A survey of its history and current status suggests that the development trend of vanadium extraction from stone coal could be concluded as follows： ① acid leaching would be preferred during the process of ore decomposition;② various methods could be used to separate and concentrate vanadium from the acid leaching solution;③ various products containing vanadium could be obtained;④ various valuable elements could be recovered in the process.
