摘要： A continuous salt-based process is provided for melting and reclaiming aluminum from aluminum scrap containing impurities including heating a molten salt in a heat bay, mixing the heated salt with aluminum scrap or skim in a charge bay to form a molten charge mixture, separating aluminum from impurities in the charge bay by coalescing aluminum to form a molten aluminum metal pad, chlorinating a portion of the charge mixture from the charge bay to form a chlorinated salt mixture and metal chlorides, removing metal chlorides from the salt mixture, and feeding the salt mixture back to the heat bay. In one aspect, the chlorinating step of the present invention includes introducing carbon monoxide or, preferably, solid carbon to control oxide concentration. The process further comprises adding fluorides and removing metal chlorides from the salt to maintain a preferred salt composition. The metal chlorides can be removed by withdrawing volatile metal chloride gases and electrolytically reducing metal chlorides in the molten salt. A further aspect of the invention permits direct reduction of oxide impurities in the salt by electrolysis. In another aspect of the invention, the scrap itself is used as a consumable heating electrode (i.e., disappearing as the scrap melts) for heating the molten salt. An additional aspect of the invention provides that the molten salt is pumped past heating electrodes, which reduces hot spots that otherwise would lead to fuming and cause instability in the molten bath composition. Yet another aspect of the invention permits removal of carbon impurities, which can be introduced to the molten salt when melting of the scrap causes pyrolysis of organic material associated with the scrap, for example, the lacquer coating on beverage cans.

摘要： A process for the recovery of metallic aluminum, mixtures of salts, and an aluminum oxide-metallic aluminum product from secondary aluminum dross. The process includes treating the dross with leach water to dissolve the salt content. Magnesium chloride is preferably added to the leach water to maintain the pH in the range of about 7-8.5, thereby reducing ammonia production in the treating step and enhancing recovery of metallic aluminum.

摘要： A method of removing skim from molten metal comprises providing a body of molten metal and passing a fluxing gas therethrough to carry skim to the surface of the metal. The skim on the surface is treated to substantially reduce the amount of molten metal contained therein and to provide the skim in a substantially powdery form. A portion of the treated skim in finely divided form is removed to a collector.

摘要： An improved method and apparatus for ingesting and melting metal scrap that otherwise tends to float on the surface of a molten melting media. The method includes the steps of providing a supply of the melting media and directing the media from the supply to an upper portion of a receptacle having an outlet opening in the lower portion thereof. The flow of the melting media entering the receptacle produces a free vortex of the media in the receptacle, as the media flows out the lower opening. The amount of the flow of the melting media to the receptacle and the size of the lower opening are such that a predetermined level of the media is maintained in the receptacle. The symmetry and continuity of the flow pattern of the vortex are disturbed in such a manner that floating metal solids (and any associated skim material) entering the vortex from the upper portion of the receptacle are rapidly ingested into the melting media. Such ingestion is much more effective than the limited ingestion capability of an undisturbed vortex.
摘要翻译：一种改进的用于摄取和熔化金属废料的方法和装置，否则其将倾向于浮在熔融熔融介质的表面上。该方法包括以下步骤：提供熔化介质的供应并将介质从供体引导到在其下部具有出口开口的容器的上部。当介质流出下部开口时，进入容器的熔化介质的流动产生介质在容器中的自由涡流。熔化介质到容器的流量和下开口的尺寸使得在容器中保持预定水平的介质。涡流的流动模式的对称性和连续性以这样的方式受到干扰，使得从容器的上部进入涡流的浮动金属固体（和任何相关的脱脂材料）被快速地吸入熔融介质中。这种摄入比不受干扰的涡流的有限摄取能力要好得多。

摘要： Disclosed is a method of melting aluminum scrap and removing skim therefrom having reduced amounts of aluminum contained therein. Melted scrap and salt is added to a body of molten aluminum in a skim removal bay and a layer containing salt and skim is collected on the surface of the body, the layer containing high levels of molten aluminum in lower regions of said layer. The layer is treated so that upper regions thereof contain reduced amounts of aluminum, the treating aiding molten aluminum in the layer to return to the body. A portion of the treated layer is removed from upper regions thereof, the portion comprised of salt, skim and aluminum.
