Vanadium Extraction from Vanadium-containing Carbonaceous Shale by Acid Leaching-Extraction-Ammonia Precipitation AITranslate
Abstract AITranslate
V2O5 was extracted from vanadium-containing; carbonaceous shale in Jiangxi using the process of carbon removal by oxidation roasting-oxidation leaching in sulfuric acid-solvent extraction in P204 ＋ TBP system-vanadium precipitation with ammonia. The effects of H2SO4 dosage,extraction and stripping stages and stripping solution pH on the process were studied. The results show that the leaching rate of vanadium can exceed 96% by vanadium ore crushing and then oxidation leaching using sodium chlorate in sulfuric acid solution. The product containing more than 98.0% V2O5 is obtained by P204＋TBP solvent extraction -dilute sulfuric acid solution stripping-vanadium precipitation with ammonia. And the total recovery of V205 is 86.14~93.09% from ore to product. The process has high vanadium recovery,simple operation, low production costs and less environmental pollution.
