Technological Study on Extraction of Vanadium and Chromium from Vanadium-bearing Chromium Residue AITranslate
Abstract AITranslate
Based on the characteristics of vanadium-bearing chromium residue from vanadium extraction,the process of NaOH alkaline leaching-H2O2 oxidation leaching was applied to extract vanadium and chromium from vanadium-bearing chromium residue.The effects were studied of material particle size,H2O2 dosage,NaOH concentration,leaching temperature and time on the leaching rate of vanadium and chromium,and the optimal leaching conditions were determined.The results show that vanadium and chromium can be effectively extracted and their leaching rates are 95.68% and 92.9%,respectively,under the conditions in the primary leaching as follows：raw material mass of 5g,particle size less than 74 mm,NaOH concentration of 100g/L,liquid-solid ratio of 10∶1,leaching temperature of 70℃and leaching time of 20 min,and the conditions in the secondary leaching as follows：H2O2 dosage of 3mL,agitating oxidation time of 30 min,leaching temperature of 95 ℃ and leaching time of 1h.
