| 摘 要： | 通过对铜转炉渣的多元素、物相分析,提出湿法处理工艺。考察物料粒度、初始酸浓度、温度、液固比、浸出时间、搅拌速度、通气速度等因素对铜、钴浸出率的影响。结果表明,采用先筛选粗粒度铜精矿后再硫酸浸出,有利于提高铜回收率,铜的累计回收率达到95%左右,钴与铁的累计回收率达到98%以上。

| Abstract: | Cobalt and copper were recovered by hydrometallurgy process from copper converter slag after multielement and phase analysis. The effects of particle size, initial sulfuric acid concentration, temperature, ratio of liquid to solid, time, stirring speed, ventilation speed and other factors on leaching rate of copper and cobalt were examined. The results show that total copper recovery rate is over 95%, cobalt and iron total recovery rate is over 98% with sulfuric acid leaching after screening coarsness copper concentrate. |
