摘　　要：这是一篇冶金工程领域的论文。以陕西某地含钒矿物为绢云母、伊利石的石煤钒矿为研究对象,采用低温硫酸熟化-水浸工艺提钒,考查了熟化温度、熟化时间、硫酸用量、氯化钠用量,浸出温度、浸出时间及浸出液固比对钒浸出率的影响。结果表明:向石煤钒矿中加入25%的硫酸、0.8%的氯化钠,在130℃下熟化8 h,熟化样品在浸出温度55℃、液固比1.5∶1的条件下浸出时间2 h,钒浸出率可达89%。这说明采用低温(130℃)硫酸熟化-水浸工艺提取石煤型钒矿是可行的。This is an article in the field of metallurgical engineering.The vanadium ore with vanadium containing sericite and illite in Shaanxi province was taken as the research object,low-temperature sulfuric acid ripening-water leaching process was used to extract vanadium.The effects of ripening temperature,ripening time,sulfuric acid dosage,sodium chloride dosage,leaching temperature,leaching time and liquidsolid ratio on vanadium leaching rate were investigated.The results show when 25%sulfuric acid and 0.8%sodium chloride are added to the stone coal vanadium ore,the sample is aged at 130℃for 8 h,and the sample is leached at 55℃for 2 h under the conditions of liquid-solid ratio of 1.5∶1,the vanadium leaching rate can reach more than 89%.This indicates that it is feasible to adopt low temperature sulfuric acid ripening and water leaching process to extract stone coal type vanadium ore.
