| 摘 要： | 根据湿法炼锌置换渣特性及不同金属属性,经酸洗选择性分离镉与铜、镓、锗,实现铜、镓、锗在固相中的高效富集;并通过采用锌粉置换高效回收酸洗富镉溶液的镉,得到镉品位20%的高镉渣。置换渣酸洗工艺中镉的高效回收有助于降低环境污染的风险,同时,铜、镓、锗在酸洗渣中的富集为后续实现资源的综合回收提供了便利。

| Abstract: | According to characteristics of replacement slag from zinc hydrometallurgy and properties of different metals, cadmium was selectively separated from copper, gallium and germanium by acid washing to achieve high-efficiency enrichment of copper, gallium, and germanium in solid phase. High-cadmium slag with cadmium grade of >20% was obtained from cadmium-rich acid washing solution by zinc powder replacement. Efficient recovery of cadmium in acid washing process of replacement slag helps to reduce risk of environmental pollution, while enrichment of copper, gallium, and germanium in acid washing slag provides convenience for subsequent comprehensive recovery of resources. |
