Study on Environment-friendly Vanadium Extraction Process by Roasting with Composite Additives and Leaching with Dilute Acid AITranslate
Abstract AITranslate
Vanadium was extracted by roasting with composite additives and leaching with dilute acid.Impacts were investigated of composite additive dosage,roasting temperature,roasting duration,sulfuric acid dosage,leaching duration,leaching temperature and liquid-solid ratio on vanadium leaching rate.The results show that under the conditions of composite additive dosage 6%,roasting temperature 800 ℃,roasting duration 3h,sulfuric acid dosage 3%,leaching duration 3h,leaching temperature 60℃and liquid-solid ratio 3∶1,the vanadium leaching rate of the above process is85.6%,increased by 13.4%compared with that of calcification roasting process.This technology has a good application prospect as an environment-friendly process with less off-gas pollution during roasting and substantially improved vanadium leaching rate.
