近年来,金属冶炼技术发展迅速,湿法炼锌技术逐渐成熟,并且成为一种应用最普遍的冶锌技术,随着湿法炼锌规模增大,每年产生的浸出渣也逐渐增多。锌矿中含有锌、银、铜等很多种有价金属,在湿法炼锌的过程中,大部分银都存在于锌浸出渣中。银不仅是一种应用广泛的金金属,可以用于装饰、感光材料等方面,还能够给金属冶炼厂带来经济效益。因此,从湿法炼锌得到的浸出渣中回收银,具有重要的研究意义。
In recent years, the rapid development of metal smelting technology, wet refining zinc technology matures, and become the most common application of zinc smelting technology, with the size of wet zinc, the leaching residue produced each year also gradually increased. Zinc ore contains many kinds of valuable metals such as zinc, silver and copper. During the wet zinc smelting process, most silver is present in the zinc leaching residue. Silver is not only a widely used gold metal, can be used for decoration, light-sensitive materials, etc., but also bring economic benefits to metal smelters. Therefore, it is of important research significance to recover silver from leaching residue obtained by wet-process zinc extraction.
