摘要
Abstract
The acidic calcified vanadium solution from Pangang Xichang Vanadium Plant was the re-search object in this study.In response to its characteristics of low acidity,high vanadium content,and difficulty in impurities removal,an extraction process was adopted to specifically remove Mn2+,Ca2+and Fe3+cations.The main influencing factors of the extraction process were investigated.And the op-timal extraction parameters were determined.The organic phase ratio was 20％P204+80％260# solvent oil with a saponification rate of 100％using ammonium hydroxide.The extractant ratio was O/A=2∶1 at the initial pH of vanadium solution of 2.9 for 5 minutes.Under the above conditions,the single stage extraction rate of Mn and Ca reach over 98％.After extraction,the Mn content drops to around 0.05 g/L,Ca,Fe and Al leves are below 0.1 g/L in acidic vanadium solution.关键词
