摘要

摘要: 综合钒渣钙化焙烧硫酸浸出液的溶液特性及其钒浓度低、杂质离子繁多的特点, 采用溶剂萃取法制得了高纯度五氧化二钒。对钒渣钙化焙烧硫酸浸出液萃取过程、洗涤过程、反萃过程、酸性铵盐沉钒过程进行了系统研究, 旨在探索出一种从钒渣钙化焙烧硫酸浸出液中清洁高效提取高纯五氧化二钒的新工艺, 为高纯度五氧化二钒技术开发与未来的生产实践提供数据支撑。结果表明:在较优的工艺条件下, 制得的精钒品位高达99.991 5%, 整个工艺的钒回收率达到88.78%。

Abstract: According to characteristics of low vanadium concentration and multitudinous impurities for the sulphuric acid leaching solution of vanadium slag roasted with calcium components,high-purity vanadium pentoxide （V₂O₅） was prepared by solvent extraction from the acid leaching vanadium-containing solution. The processes of extraction,washing,stripping and acidic precipitation of vanadium by ammonium salt were systematically researched in order to explore a completely clean and efficient method for extracting vanadium from acid leaching vanadium-containing solution and provide data support for the development and application of high-purity V₂O₅ preparation technology. The results show that V₂O₅ with 99.991 5% of purity can be obtained and the recovery rate of vanadium for the whole process is up to 88.78% under the optimal conditions.
