Abstract
An improved method of separating organic solvents from aqueous process streams is disclosed in connection with a copper solvent extraction/electrowinning process. An aqueous solution having droplets of an organic solvent entrained therein is admitted to the upper part of a vertically extending vessel, and air bubbles are passed therethrough from an air inlet near the bottom of the vessel. The aqueous solution is continually removed from a point at the bottom of the vessel beneath the point at which the bubbles are admitted, such that countercurrent flow of the bubbles and solvent occurs. The bubbles bind the droplets of organic solvent and can be controlled to form a froth on the upper surface of the solution within the vessel. The froth can readily be collected and the organic solvent condensed therefrom.
