Abstract

An apparatus for the electrolytic recovery of metals from liquid solutions containing recoverable metal values. The apparatus comprises a housing containing a tubular cathode concentrically disposed about and radially spaced from an elongated anode for defining a solution-containing volume there-between. An elongated tubular baffle means having a plurality of thoroughgoing perforations through the side wall thereof and along the longitudinal length thereof is disposed about a substantial length of the anode and is in registry with the inlet to a solution pumping means located within the housing that is utilized for circulating the solution in a helical flow pattern within the housing volume. As the solution is circulated by the pumping means, a substantial volume of the solution passes into the baffle means through its open end and through the perforations so that the presence of the baffle means inhibits the formation of vortices in the circulating solution and provides for uniform solution distribution within the volume to assure the presence of metal at the cathode even during relatively low concentrations of the metal in the solution. The housing is supported on a base containing the drive means for the pumping means in such a manner that it can be readily removed from the base for facilitating the removal of the collected metal from the cathode.
