摘要： A method of recovering aluminum is provided. An alloy melt having Al4C3 and aluminum is provided. This mixture is cooled and then a sufficient amount of a finely dispersed gas is added to the alloy melt at a temperature of about 700° C. to about 900° C. The aluminum recovered is a decarbonized carbothermically produced aluminum where the step of adding a sufficient amount of the finely dispersed gas effects separation of the aluminum from the Al4C3 precipitates by flotation, resulting in two phases with the Al4C3 precipitates being the upper layer and the decarbonized aluminum being the lower layer. The aluminum is then recovered from the Al4C3 precipitates through decanting.

摘要： A container for a material, said container having a liner comprised of an equilibrated reaction product of the material. Preferably, the material is a molten aluminum-lithium alloy and the reaction product consists essentially of lithium aluminate. A method of making the container comprises shaping a substance into a vessel, said substance having sufficient porosity to react with the material and form a non-wetting reaction product without spalling; and introducing the material to the vessel. A method of making a container liner by applying a substance to the container inner surface and introducing the alloy to the inner surface is also disclosed.

摘要： Apparatus, systems and methods for carbothermically producing aluminum are disclosed. The systems may include a reactor and an electrical supply. The reactor may include a plurality of side-entering electrodes and a top-entering electrode. The electrical supply may be operable to supply multiphase current to the side-entering electrodes and/or the top-entering electrodes. The electrodes may be in communication with a molten bath of the reactor, and the multiphase current supplied thereto may be passed through the bath to heat the reactor. The amount of current supplied to various electrode sets may be adjusted to facilitate tailored heating of the molten bath.

摘要： This invention relates to the use of bubble-driven flow to enhance the dissolution and distribution of alumina in an aluminum electrolysis cell operating with inert anodes. By harnessing the driving force of bubbles rising along the sides of a sloped anode to induce circulation in a cell and by using a group of anodes to amplify the effect, alumina distribution can be maintained close to or at saturation without formation of muck/sludge. Alumina fed through point feeders at specific locations can be distributed throughout the entire cell rather than sinking to the bottom of the cell below the feed location. For a given circulation pattern, feeder locations can be optimized.

摘要： In a system for treating and managing hot aluminum dross, the dross is compacted and delivered by a pair of "squeeze" rolls in a continuous semi-solid sheet, readily broken up for further treatment or disposal. The rolls may be cooled or heated as required to condition the dross appropriately, for storage or immediate further treatment. Ribs on the rolls and/or a stepped "break" chute downstream of the rolls may be used to break the compacted dross into "patties" for convenient handling.
