红热钒渣吹氧氧化仅１０ｍｉｎ左右，经碱浸压煮提钒，钒浸出率可达９０％以上．吹氧过程中，增添ＣａＯ，控制合适的ＭｇＯ与钒渣的重量比，减小供氧速率，可获得高的．碱浸时，钒浸出率主要随的增大而升高．保温时间、浸出温度、Ｎａ２ｃｏ３和ＮａｏＨ的加入比、渣水质量比对钒浸出率都有影响．碱浸压煮时充氧和水洗残渣也可以提高钒的总浸出率．
Red hot vanadium slag blowing oxygen oxidation only about 10min, the alkali dip cook cooking vanadium, vanadium leaching rate of up to 90%. Oxygen blowing process, add CaO, control the appropriate weight ratio of MgO and vanadium slag, reducing the oxygen supply rate can be obtained high. Alkali leaching, the vanadium leaching rate increases with the main increase. Holding time, leaching temperature, addition ratio of Na2co3 and NaoH, slag water quality ratio have an impact on the vanadium leaching rate. Alkaline immersion cooking oxygenation and washing residue can also improve the total leaching rate of vanadium.
