| Abstract: | 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. |
