Study on Vanadium Extraction from Direct Acid Leaching Solution of Carbonaceous Shale Vanadium Ore AITranslate
Abstract AITranslate
Investigation is made on the amount of the residual elements by ICP-AES and ICP-MS during va- nadium extraction from direct acid leaching solution of carbonaceous shale vanadium ore. During alkali addition for impurity removal,vanadium retention rate is high at pH of 2.8 and 12.2,and element retention rate-pH curves are divided into four groups： U-type curves, descending curves, ascending curves and horizontal curves. During oxidation,four kinds of oxidants were added into the solution with the pH of 2.8 and 12.2. In terms of oxidation effect and production cost,the use of Na2S2O8 with pH of 2.8 can result in optimal oxidization effect. Extraction-stripping cannot remove Na impurity of the highest content, but it can greatly increase the content of P impurity instead. The necessity of extraction-stripping is to be further studied
