| 摘 要： | 以某炼锌厂堆放的浸锌渣为对象,采用硫酸酸浸的方法,对影响Zn、Ge浸出的因素进行条件试验。结果表明,在磨矿细度为-0.074mm占78.68%、氟化铵用量50mL(浓度5%)、硫酸用量120mL(浓度30%)、液固比4∶1、浸出温度85℃,浸出时间3h的条件下,可获得93%以上的Zn浸出率和90%以上的Ge浸出率。

| Abstract: | With zinc leaching residue as raw materials,leaching test of zinc leaching residue with sulfuric acid was carried out to investigate influence factors on leaching of zinc and germanium.The results show that leaching rate of Zn and Ge is 93% above and 90% above respectively under the conditions including grinding fineness of-0.074 mm of 78.68%,ammonium fluoride dosage of 50 mL(concentration of 5%),sulfuric acid dosage of 120 mL(concentration of 30%),L/S of 4∶1,leaching temperature of 85 ℃,and leaching time of 3 h. |
