| 摘 要： | 湿法炼锌是当今世界炼锌主要方法，生产中所得锌浸渣中含有较多的锌及其他有价金属(如银、铅、铜、镉、铟、锗等)，作为尾矿堆存不仅会占用大量的土地资源，而且还会造成资源的严重浪费，加之锌浸出渣的长期堆存环境危害性高，因此对锌浸出渣中的有价金属进行综合回收具有十分重要的意义。本文结合国内外锌浸出渣的研究状况，重点针对锌浸出渣中银的回收现状进行论述，全面阐述锌浸出渣中银的工艺矿物学性质、提取工艺流程及发展趋势，对该类资源的综合回收利用具有十分重要的借鉴作用。

| Abstract: | Hydrometallurgy is the main method of zinc smelting in the world today. The zinc-leached residues produced from zinc hydrometallurgy contain zinc as well as other valuable metals such as silver, lead, copper, cadmium, indium, germanium, etc. As a tailings storage, the residues not only occupy a large amount of land space, but also cause serious losses of valuable resources. In addition, the long-term storage is highly hazardous to the environment. Therefore, it is of great significance to comprehensively recover valuable metals from the zinc-leached residues. Based on the research status at home and abroad, a review was made on this aspect in the present paper, including the process mineralogical properties of the zinc-leached residues, extraction process and development trend. |
