Abstract AITranslate

In this paper,stone coal vanadium ore was used as raw material,and the vanadium was extracted by barium salt roasting-low acid leaching process from the concentrate after tailing discarding and enrichment.The effects of concentrate roasting and leaching conditions on the leaching rate of vanadium were studied.The results show that the average vanadium leaching rate can reach 87.93%under the optimal conditions of stone coal vanadium concentrate fineness of 70%passing 74μm,roasting temperature of 925℃,roasting time of 6 h,barium sulfate dosage of 4%concentrate quality,liquid-solid ratio in leaching process of 2∶1,sulfuric acid dosage of 5%calcine quality,leaching temperature of 50℃and leaching time of 1 h.The process has the advantages of high vanadium leaching rate,low acid dosage,low extraction cost and simplified subsequent vanadium extraction process.
