An economic and technical assessment of black-dross and salt-cake-recycling systems for application in the secondary aluminum industry
The secondary aluminum industry annually disposes of large amounts of dross residues and salt cake, which are by-products from the processing of scrap aluminum for reuse. These wastes contain as much as 50% salts and are presently disposed of in conventional landfills. As the costs of landfill space increase and the availability of landfill space decreases, disposal of the residues will increasingly compromise the economics of recycling aluminum. Alternative processes exist by which the major constituents of the various drosses and salt cakes can be recovered for recycling. In this study, we review available recycling technologies and processes relevant to the recycling of black dross and salt cake and discuss new concepts that have the potential to improve the cost-effectiveness of recycling technologies.
