Abstract: A rotary furnace includes a drum and a frame supporting the drum for rotation about a nominally horizontal rotational axis. The frame and the drum are supported for pivotal movement about a horizontal pivotal axis. A door supported on the frame normally closes the front end of the drum and is selectively pivotal to an open position to facilitate charging of the drum. The door includes a pouring door which is openable to facilitate discharge of molten material from the drum.

Abstract: A method for recovering aluminum metal from varied size clumps of salt cake. The salt cake clumps have varied concentrations of aluminum metal.

Abstract: 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.

Abstract: Spent potlinings from aluminum reduction cells are fed to an aluminum reclamation furnace as a partial replacement for or supplement to the molten salt flux used in the reclamation process. This rids the spent potlinings of materials which would leach into soil or groundwater if the potlinings 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 for the salt flux materials and by using the fuel potential of the potlinings to reduce the external fuel requirement.
