摘要
介绍了用灼烧、浸取、沉淀、溶转和离子交换等方法 ,从银铅锌废渣中直接回收硝酸银 ,收率可达 80 .12 % ,Ag NO3纯度为 99.9%。考察了试料粒度、Fe Cl3质量浓度、溶液酸度、固液比。
A study on direct recovery of silver nitrate from silver zinc lead containing slag via roasting leaching precipitation dissolving and conversion ion exchange processes has been carried out with 80.12 % of silver yield and 99.9% of AgNO 3 purity. The factors affecting silver yield such as slag granularity, FeCl 3 mass concentration,solution acidity,reaction temperature and leaching time were examined in the study.
