摘要
采用硝酸浸出的方法从锑精炼除铅渣中回收金属铅,考察了液固比、浸出温度和时间、硝酸浓度等对铅浸出率的影响。结果表明,适宜的浸出工艺为:液固比4、浸出温度80℃、浸出时间50min、硝酸浓度7.0mol/L。在此条件下,铅浸出率可以达到94%。
Lead was recovered from lead slag of antimony refining by nitric acid leaching process. The effects of ratio of liquid to solid （L/S）, leaching temperature and time, and nitric acid concentration on lead leaching rate were investigated. The results show that the lead leaching rate is above 94; under the optimum conditions including L/S of 4, leaching temperature of 80℃, leaching time of 50 min, and nitric acid concentration of 7.0 mol/L.
