Summary: Solvent sublation is a combined method that includes advantages of ionic flotation and liquid extraction. This is a process in which flotation product (sublate) concentrates in a thin layer of organic liquid, which is located on the surface of aqueous phase. The research of zinc ions by solvent subltation from model solutions allowed to determine rational conditions of process: pH 7, molar ratio of Zn2+:surfactant = 1:2, the volume of organic phase 5 cm3. Under these conditions removal ratio of zinc ions into isoamyl alcohol is 95%.
Key words: zinc, solvent sublation, removal ratio, sublat.
