    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: An apparatus to electrolytically produce multivalent metals, such as titanium, from compounds thereof. The apparatus includes a suitable containing body with an anode and a cathode in compartments therein spaced apart by a foraminous metallic diaphragm. The diaphragm has a diaphragm coefficient of greater than zero to about 0.5 when the coefficient of flow is about 0.1 to about 25. A multivalent metal compound feed means is combined with the cathode compartment to supply a multivalent metal compound to a molten salt electrolyte in the cathode compartment. The apparatus is sealed from the atmosphere to avoid contamination of the bath and metal product with certain atmospheric gases. Means of providing sufficient electrical and thermal energy to operate the cell are provided.

    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: The presently disclosed concepts relate to improved techniques for critical mineral extraction, purification, precipitation, ion exchange, and metal production using a solid electrolyte membrane. By using a solid electrolyte embedded in a matrix, alkali metal (such as lithium) can be more effectively separated from feed solutions. Additionally, energy used to initially extract critical minerals from a feed solution may be stored as electrochemical energy, which in turn, may be discharged when critical minerals are depleted from the electrode. This discharged energy may therefore be reclaimed and reused to extract additional critical minerals.
