Abstract: An electrolytic cell for the recovery of material as a powder or flakes from a solution, includes a cell cavity for containing the solution, a rotatable electrode in the cavity having a pair of opposite electrode faces, and a counter electrode in spaced and opposing relationship with the respective opposite electrode faces of the rotatable electrode to supply a current through solution in the cavity to permit extraction of the material by electrochemical reaction. A vibrator directs vibrational energy toward the rotatable electrode to dislodge material extracted as a powder or flakes from the solution by an electrochemical reaction.

Abstract: Disclosed is an electrolytic cell for removal of material from a solution. The cell comprises a cavity for receiving the solution, a rotatable electrode located within the cavity, a counter-electrode in spaced relation to the rotatable electrode, and an ultrasonic generator coupled to said cavity for directing ultrasonic energy toward the rotatable electrode to displace solid material extracted from the solution by an electrochemical reaction. The rotatable electrode may form a cathode, and the counter-electrode may form an anode, wherein metal in the solution is deposited on the cathode as a metal powder, such that the ultrasonic energy displaces the metal powder from the cathode. Alternatively, the rotatable electrode may form an anode, and the counter-electrode may form a cathode, wherein organic waste in the solution is deposited on the anode, such that the ultrasonic energy removes the deposited organic waste from the anode.
