Abstract: Modular cathode assemblies are useable in electrolytic reduction systems and include a basket through which fluid electrolyte may pass and exchange charge with a material to be reduced in the basket. The basket can be divided into upper and lower sections to provide entry for the material. Example embodiment cathode assemblies may have any shape to permit modular placement at any position in reduction systems. Modular cathode assemblies include a cathode plate in the basket, to which unique and opposite electrical power may be supplied. Example embodiment modular cathode assemblies may have standardized electrical connectors. Modular cathode assemblies may be supported by a top plate of an electrolytic reduction system. Electrolytic oxide reduction systems are operated by positioning modular cathode and anode assemblies at desired positions, placing a material in the basket, and charging the modular assemblies to reduce the metal oxide.

Abstract: The invention relates to a process that allows electrolytic copper cathodes to be produced, using the pregnant leach solution (PLS) directly in the electrowinning, avoiding the step of mineral concentration by solvent extraction. Furthermore, this process has a modular structure and the full process can be mobilised depending on the requirements of the process itself. The invention also relates to the system that operates with the previously described process.

Abstract: An anode assembly is provided having a pair of channels; anodes in slidable communication with the channels; conduit to direct carrier gas to the anode; and conduit to remove reaction gas from the anode. Also provided is a method for continuously feeding anodes into a electrolytic bath, the method having the steps of stacking the anodes such that all of the anodes reside in the same plane and wherein the stack includes a bottom anode; contacting the bottom anode with the electrolytic bath for a time and at a current sufficient to cause the bottom anode to be consumed during an electrolytic process; using gravity to replace the bottom anode with other anodes defining the stack.

Abstract: A method for recovering heavy metals and rare earth elements from fly ash, coal ash, and unrefined mineral ores containing rare earth metals using an ionic liquid and an organic acid to solubilize the metals. The solubilized components are removed from the ionic liquid by electrochemical deposition. The heavy metals and rare earth elements are deposited onto an electrode, and then purified via electrochemical processing.

Abstract: A galvanic cell and methods of using the galvanic cell is described for the recovery of uranium from used nuclear fuel according to an electrofluorination process. The galvanic cell requires no input energy and can utilize relatively benign gaseous fluorinating agents. Uranium can be recovered from used nuclear fuel in the form of gaseous uranium compound such as uranium hexafluoride, which can then be converted to metallic uranium or UO2 and processed according to known methodology to form a useful product, e.g., fuel pellets for use in a commercial energy production system.
