摘要
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．
The hot V slag were first oxidized ouly 10 odd min.with blowing oxygen and then were alkaline leached,the leaching ratio of V come up to 90%.Higher can be obtained in case of increasing the addition of CaO into V slag,weight ratio of MgO and slag is controlled in optimum range, and decreasing the rate of oxygen supply in blowing oxygen process,Leaching ratio of V increases major with the increases of Holding time,leaching temperature,the addition ratio of Na2CO3,and NaOH,and the weight ratio of slag and water influence the leaching ratio of V.The total leaching ratio of V increases with the oxygenation during V slag alkaline autoclave leaching and during residuel slag water leaching.
