研究了采用"酸浸—P204萃取—硫酸反萃取—氨水沉淀—煅烧制精钒"工艺流程从西北含钒石煤中提取五氧化二钒。试验研究及工业应用结果表明,在无氧化剂存在下,于85℃、液固质量比1∶1、矿石粒度-60目条件下,用硫酸溶液可以浸出石煤中约80%的钒。用P204和TBP的磺化煤油溶液萃取、硫酸溶液反萃取,可得到较纯的五氧化钒溶液,再经氨水沉淀、热解,可得到纯度98%以上的精钒产品。
Abstract：Extraction of V2O5 from stone coal containing Vanadium from Westnorth China is investigated. The results show that Vanadium of about 80% can be leached with sulfuric acid under the condations that temperature is 85℃, mass ratio of liquid and solid is 1∶1, ore size is -60 mesh. Then puritic solution containing V2O5 can be acquired after being extracted with P204 and TBP dissolved in sulfonated kerosene and stripped with sulfuric acid. Refine V2O5 (purity is 98%) can acquired by precipitating with ammonium water and pyrolysis.
