| 摘 要： | 采用选择性浸出—萃取工艺对湿法炼锌酸浸铜渣进行综合回收,通过单因素试验和扩大试验考察氨水浓度、氧化剂用量、浸出时间、浸出温度对浸出率的影响。结果表明,铜、锌浸出率分别达到96.5%、86%以上,铁、铅浸出率分别在3%、1.2%以下,大大降低了工艺成本。

| Abstract: | Copper acidic slag from zinc hydrometallurgy was comprehensively recovered applying selective leaching and extraction. Effects of ammonia water concentration, oxidant dosage, leaching time, and leaching temperature on leaching rate were investigated by single factor experiment and expanding test. The results show that leaching rate of copper and zinc is 96.5% and 86% above respectively, leaching rate of iron and lead is 3% and 1.2% below respectively. Sharply reduction of cost is achieved. |
