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.
