·Recycling aluminium in a rotary furnace with salt fluxes allows recovering valuable alloys from hard to recycle waste/side streams such as packaging dross and incinerator bottom ash However this recycling route generates large amounts of salt slag/salt cake hazardous wastes which can pose critical environmental risks if landfilled
·The result of the experimental study was that the metal yield of the dross used in the melting experiment at the Chair of Nonferrous Metallurgy was higher than that achieved by external reprocessing
·November/December 2018 Aluminium International Today 12 SECONDARY Sales Manager PyroGenesis Canada Sustainable and profitable dross practices For the aluminium industry the subject of dross has become a point of frustration Globally regulatory bodies have been steadily
·In plant aluminum dross recovery has been available for some time but isn t widely used for small volumes of dross Crucible melting furnaces typically generate 5 25 lb of dross and most recovery equipment has been considered too cumbersome to move from furnace to furnace most operations try to reduce the metal content of the drosses

·Melting and refining Traditional furnaces with fluxing agents can melt dross and separate molten aluminum from impurities Salt slag processes Specialized processes like the Rotary Salt Furnace RSF or the Aluminum Salt Bath ASB use molten salt baths to efficiently separate aluminum from oxide
