摘要： Scrap aluminum is reclaimed by a salt flux-based reclamation process using potassium chloride in place of the commonly used sodium chloride. The spent flux which remains after the recovery of the aluminum is useful as a soil fertilizer, with the potassium content of the flux serving as a source of potassium nutrient for the soil. The potassium in the spent flux is highly water soluble at all values of pH while the aluminum in the spent flux remains at a limited solubility, particularly under the conditions expected to be encountered in soil. Thus, despite the known phytotoxicity of aluminum and the presence of aluminum in the spent flux, the spent flux is discovered to be useful as a plant fertilizer with the maximum benefit from the potassium and minimal if any harm from the aluminum.

摘要： A method for recovering aluminum metal from varied size clumps of salt cake. The salt cake clumps have varied concentrations of aluminum metal. The method includes steps of segregating (14) the varied size clumps into smaller clumps and larger clumps, by size; separating (22), by aluminum metal concentration, the larger clumps into clumps of higher aluminum metal concentration and reject clumps of lower aluminum metal concentration; impacting (24) the reject clumps to size-reduce the clumps to smaller reject clumps; returning the smaller reject clumps after impacting to the previous step of segregating; segregating (20) the smaller clumps from the step of segregating into large clumps and small clumps, by size; separation (28), by aluminum metal concentration, the small clumps into clumps of higher aluminum metal concentration and second reject clumps of lower aluminum metal concentration; and separating (30) the second reject clumps into clumps of higher and lower aluminum concentration.

摘要： Spent potlinings from aluminum reduction cells are fed to an aluminum reclamation furnace (10) as a partial replacement for or supplement to the molten salt flux used in the reclamation process. This rids the spent potlinings (14) of materials which would leach into soil or groundwater if the potlinings (14) were otherwise disposed of at dumpsites, rendering them suitable for dumping with no hazard to the environment. Benefits to the reclamation process may be had at the same by substituting the less expensive potlinings (14) for the salt flux materials and by using the fuel potential of the potlinings (14) to reduce the external fuel requirement.

摘要： Les garnissages de creusets usés provenant de cellules de réduction en aluminium, sont amenés à un four de récupération (10) d'aluminium, comme remplacement ou supplément partiel du fondant salin fondu, utilisé dans le processus de récupération. L'invention permet de se débarrasser des garnissages de creusets usés (14), de matières qui s'infiltreraient dans le sol ou dans la nappe souterraine si lesdits garnissages de creusets (14) étaient mis au rebut différemment sur des sites de décharges, en les rendant adaptés à une mise au rebut sans danger pour l'environnement. On peut également retirer des avantages dudit processus de récupération, en remplaçant les garnissages de creusets (14) moins chers par les matières de fondant salin et en utilisant le potentiel de combustibles desdits garnissages de creusets (14) afin de réduire le besoin en combustibles.
