Residues From Aluminium Dross Recycling In Cement

3 This case study investigates the use of aluminium oxides generated from dross processing, in cement. The terms non-metallic residues, aluminium oxides and salt cake are used interchangeably in this case study. Potential applications for white/black dross The composition of aluminium dross is highly variable and usually unique to the plant generating the waste, hence finding potential .

Aluminum residue waste for possible utilisation as a

cement or inert aggregates in the production of mortar and concrete. Similarly, aluminium refining industries produce different solid wastes. Disposal and recycling of aluminium dross produced during aluminum melting is a global issue. Mostofthe dross isbeing disposed off in landfill sites,which results in leaching of toxic metal ions into

Black Dross Leached Residue: An Alternative Raw Material

Abstract The possibility of adding an aluminium black dross leached residue (BDLR), mainly consisted of spinel (Al 2MgO 4) and corundum (Al 2O 3), in the raw meal for the production of Portland cement clinker was investigated. This leached residue was obtained during the hydrothermal treatment of an aluminium black dross, formed during

Recovery of Metals from Aluminum Dross and Saltcake

Various aluminum-smelting by-products from three production sources were received and characterized. The waste materials were tested for compound identification and environmental acceptance. A coarse metallic aluminum recovery test using an Eddy Current separator (ECS) was performed using two different Circuit configurations. White dross performed equally well with either Circuit, while black
