Flotation by means of microgas dispersions was used to remove copper, chromium, nickel, lead, and zinc from aqueous solutions, including an industrial plating effluent. Metal removals of up to 100% were obtained from solutions of the metals ranging in concentration from 2 to 20 ppm. © 1982 by Marcel Dekker, Inc. All rights reserved.
