摘要：
A process flowsheet for zinc recovery from galvanized steel scrap in alkaline media has been studied. The process includes leaching of zinc by sodium hydroxide followed by solvent extraction using organic extractants containing oxine derivatives, such as Kelex 100, LIX-26. Zinc was stripped from the loaded organic by sulphuric acid, which was then recovered by precipitation as zinc carbonate.
