摘　　要：以某低热值含钒石煤配煤燃烧灰渣为研究对象,进行了直接酸浸提钒的试验研究。通过单因素条件试验,确定了浸出液固比、硫酸用量、助浸剂添加量、浸出温度、浸出时间、搅拌速度等工艺条件。在最佳浸出条件下,灰渣中钒的浸出率大于79%。The experimental study of vanadium extraction was carried out by direct acid leaching from the burning ash of low-calorific-value vanadium-bearing carbonaceous shale blended with coal.Based on single factor tests,the process conditions were determined including leaching liquid-solid ratio,dosage of sulfuric acid and aid leaching agent,leaching temperature,leaching time and stirring speed.Under the optimum leaching conditions,the leaching rate of vanadium in the ash is over 79%.
