  • Electrolyte circulation manifold for copper electrowinning cells which use the ferrous/ferric anode reaction
    Patent number: 5492608
    Abstract: An improved electrolyte circulation manifold system for use in a copper electrowinning cell which includes an array of alternating cathode and anode plates positioned within a holding tank is disclosed. The manifold system itself includes a first manifold section positioned within the holding tank adjacent to a first lateral edge portion of each cathode plate and anode plate in the array. The first manifold section includes a first plurality of holes formed along it's length so that each hole is oriented in a horizontal plane and a single hole is positioned between and facing each anode plate and an adjacent cathode plate. A second manifold section is positioned within the holding tank adjacent to a second lateral edge portion of each cathode plate and anode plate in the array.
