Abstract: A method is provided for producing metal by electrolytic reduction of a feedstock comprising an oxide of a first metal. The method comprises the steps of arranging the feedstock in contact with a cathode and a molten salt within an electrolysis cell, arranging an anode in contact with the molten salt within the electrolysis cell, and applying a potential between the anode and the cathode such that oxygen is removed from the feedstock. The anode comprises a second metal, which at the temperature of electrolysis within the cell is a molten metal. The second metal is a different metal to the first metal. Oxygen removed from the feedstock during electrolysis reacts with the molten second metal to form an oxide comprising the second metal. Thus, oxygen is not evolved as a gas at the molten anode.

Abstract: A method of recovering metals from electronic waste comprises providing a powder comprising electronic waste in at least a first reactor and a second reactor and providing an electrolyte comprising at least ferric ions in an electrochemical cell in fluid communication with the first reactor and the second reactor. The method further includes contacting the powders within the first reactor and the second reactor with the electrolyte to dissolve at least one base metal from each reactor into the electrolyte and reduce at least some of the ferric ions to ferrous ions. The ferrous ions are oxidized at an anode of the electrochemical cell to regenerate the ferric ions. The powder within the second reactor comprises a higher weight percent of the at least one base metal than the powder in the first reactor. Additional methods of recovering metals from electronic waste are also described, as well as an apparatus of recovering metals from electronic waste.

Abstract: Compositions suitable for use in an electrolytic cell for producing aluminum are provided. The compositions can contain a powder blend of boron oxide, a titanium dioxide, aluminum, and titanium diboride. The powder blend can be compacted into tiles and arranged as a cathode surface. The boron oxide and the titanium dioxide in the tiles can be made to react under low temperature molten aluminum to produce titanium diboride in situ. The reaction yields a dense dimensionally stable wettable cathode substrate that can reduce the power consumption in the aluminum electrowinning process.

Abstract: Lead is recycled from lead paste of lead acid batteries in a process that employs alkaline desulfurization followed by formation of plumbite that is then electrolytically converted to pure lead. Remaining insoluble lead dioxide is removed from the lead plumbite solution and reduced to produce lead oxide that can be fed back to the recovery system. Sulfate is recovered as sodium sulfate, while the so produced lead oxide can be added to lead paste for recovery.

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.

Abstract: Cathode plate edge protector systems formed by secondary and tertiary molding processes, in which fluid plastic is molded around and/or introduced into previously manufactured plastic edge protectors. A U-shaped edge protector system is formed by bevel-cutting abutting ends of edge protector strips, securing the strips in the desired configuration a molding jig, and molding corner pieces around the abutting ends. The system is then removed from the jig and slip-installed over the two sides and the bottom edge of a cathode plate. In an optional tertiary molding process, fluid plastic may be introduced into the remaining void between the edge protector system and the cathode plate. Another edge protector system is formed by mounting edge protector strips on opposing side edges of a cathode plate, damming the open ends, and introducing fluid plastic in the contained voids between the strips and the cathode plate.
