摘要： A method of electrolytic reduction of a feedstock comprising oxygen and a first metal 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, the anode comprising a molten second metal and applying a potential between the anode and the cathode such that oxygen is removed from the feedstock to form a reduced feedstock. The oxygen removed from the feedstock reacts with the molten second metal to form an oxide comprising the second metal. The second metal is aluminium. The reduced feedstock may comprise a proportion of aluminium.

摘要： There is described a method of reprocessing spent nuclear fuel. The spent nuclear fuel is added to an electro-reduction cell containing a halide salt electrolyte at a temperature above the melting point of the metallic form of uranium and higher actinides present in the spent nuclear fuel. The cell is operated so as to electrochemically reduce the spent nuclear fuel to form an alloy of uranium and higher actinides present in the spent nuclear fuel, wherein electrochemical reduction is continued until a concentration of unreduced components of the spent nuclear fuel is sufficiently low for the alloy to agglomerate.

摘要： The subject invention pertains to methods for processing a solid material (M1X) comprising a solid solution of a non-metal species (X) in a metal or semi-metal (M1) or a compound between the non-metal species and the metal or semi-metal is immersed in a molten salt (M2Y). A cathodic potential is applied to the material to remove a portion of the non-metal species by electro-deoxidation. To remove the non-metal species at lower concentrations, a source of a reactive metal (M3) is immersed in the molten salt and is electronically connected to the material. Reactions occur at the material, where the non-metal species dissolves in the salt, and at the reactive metal, which reacts with the non-metal species dissolved in the salt to form a reaction product more stable than a compound between the non-metal species and the metal or semi-metal (M1). The non-metal species is thus removed from the solid material.

摘要： An electroslag-cold hearth (ESCH) system for refining or producing a desired metal or metal alloy is described. The system includes at least one cold hearth vessel capable of holding a pool of molten liquid metal and an overlying slag layer, and an ingot mold laterally off-set from the cold hearth. A source of raw material, e.g., a feed electrode, is positioned above the cold hearth, and fed into the molten slag in a refining operation. A flow-over dam separates the ingot mold from the cold hearth, preventing the flow of inclusions and other foreign bodies into the ingot mold. In some instances, a non-consumable electrode provides additional thermal energy to the slag. In the production operation, the metal source can be a salt from which the desired metal can be electrochemically extracted. Related methods for refining or producing metals such as titanium alloys are also described.

摘要： The present invention concerns a procedure for continuous or batch production in one or possibly more steps in one or more furnaces of silicon metal (Si), possibly silumin (AlSi alloys) and/or aluminium metal (Al) in the required conditions in a melting bath, preferably using feldspar or feldspar containing rocks dissolved in a fluoride and process equipment for implementing the procedure. Highly pure silicon is produced by electrolysis (step I) in a first furnace comprising a replaceable carbon anode (3) located at the bottom of the furnace and a carbon cathode (1) located at the top of the furnace. For the production of silumin the Si-poor residual electrolyte from step I is transferred to a second furnace and aluminium metal is added (step II). Aluminium metal is produced in a third furnace (step III) by electrolysis after Si has been removed in step I and possibly in step II. The present invention also concerns the production of silicon, possibly silumin and/or aluminium by using process equipment comprising tow or more furnaces integrated to form one unit with (an) intermediate partition wall(s) which is/are designated to transfer the electrolyte from one furnace to another.
