    Abstract: A method and apparatus for extraction of zinc ore is disclosed. The zinc ore is mixed with a dilute acid, typically sulfuric acid, in a leaching process and is thereafter filtered through an appropriate number of stages. The filtration removes some of the heavier metals such as lead. Purification removes other elements, typically copper and cadmium. After purification, the filtrate is introduced on the cathode side of a tank having an anode and cathode separated by a permeable diaphragm. The elemental zinc deposits on the cathode while reconstituted acid accumulates on the anode side. The acid is recovered and recycled to the leaching step. The rate of recovery of zinc at the cathode is substantial.

    Abstract: A porous layer is provided on one or both surfaces of a mass-transfer membrane to enhance or modify the passage of ions. The membrane may be a film of any of a variety of polymeric materials, and the porous layer may be a surface layer on the membrane or a separate porous structure placed in contact therewith. The porous layer or layers render certain normally ion-impermeable polymeric films capable of passing ions in an electrodialysis-type system.

    Abstract: Feed cathode for an electrolytic cell with a feed conduit suited to pass a metal compound therethrough from a source to an electrolyte in the cell. The feed cathode includes a member surrounding and substantially entirely enclosing at least an outlet of the conduit. The member is at least partially formed of an electrically conductive foraminous body suited to pass the electrolyte and ions of a multivalent metal compound therethrough. Preferably, the foraminous body has an electrical coefficient of greater than zero to about 1 and a flow coefficient of from about 0.1 to about 300.

    Abstract: A method for electrolytic deposition of metals, particularly zinc, in which the tendency for the cathode to be attacked in the immediate vicinity of the solution level is eliminated or greatly reduced by positioning a barrier structure in the cell assembly in a manner such that it extends from slightly above to slightly below the level of the solution in the cell. The barrier, which may be of any material resistant to attack by the electrolytic solution, prevents the migration of the oxygen at the solution level and thus protects the cathode from solution level attack.

    Abstract: An electrolyte process for the recovery of nickel or zinc from solutions wherein the anions are substantially purely chloride comprises introducing the solution into a cathode compartment of an electrolytic cell which is divided into three compartments namely an anode compartment, a cathode compartment, and an electrolyte compartment therebetween, the anode compartment being defined by a porous diaphragm of low permeability which separates the anolyte from the electrolyte, the anolyte comprising a solution containing anions which have an oxidation potential sufficiently high to ensure that substantially only the decomposition of water takes place at the anode under operating conditions and wherein the cathode compartment is defined by a diaphragm of relatively high permeability.
