| 摘 要： | 采用分段溶解法提取石煤中的五氧化二钒，浮选去除石煤中大部分碳后，先在稀盐酸介质中溶解氧化物中的钒，然后用盐酸和亚铁盐浸取硅铝酸盐中钒，使大部分钒转入溶液中，浸出液经氧化处理料液后，料液经过离子树脂交换，一次提取即可获得纯度达97.0%的五氧化二钒产品，钒回收率在85%以上。

| Abstract: | V 2 O 5 was extracted from Stone coal with a dissolution of two steps. After the removal of Carbon by flotation, the vanadium pentoxide was dissolved in HCl dilute solution, and then the vanadium associated with silica-alumina minerals was leached out with FeSO 4 .The leaching liquor was treated with oxidation and ion resin exchange. The leaching liquor was obtained with a grade of 97.0% V 2 O 5 and a recovery of 85.0%. |
