Simultaneous Removal of Al, Cu and Zn Ions from Aqueous Solutions Using Ion and Precipitate Flotation Methods

This paper presents the results of investigations concerning simultaneous removal Al(III), Cu(II), and Zn(II) from dilute aqueous solutions using ion precipitate flotation methods. The effects initial solution pH, surface active substance concentration, gas velocity on flotations’ efficiency course are studied. Experimental discussed in terms physicochemical aspects related to metal salts. indicate that satisfying flotations aluminum, copper zinc species observed if pH value ranges between 7.0 9.0. It was found an increase collector concentration a decrease rate constants. An rates.
