 · Saltcake is the slag generated during the recovery of aluminum in Rotary Furnaces. To maximize metal recovery, a salt flux is often added to aluminum scrap and dross in the recovery process, and the residue resulting from that aluminum recovery process is referred to as saltcake or saltslag. Saltcake typically contains 310% metallic aluminum, 2060% aluminum oxide, and 2080% salt.

"Black dross" or "salt cakes" refer to aluminum dross from practices that use salt fluxes. The dross is crushed, screened and melted in a rotary furnace where the molten aluminum is collected in the bottom. The resulting salt slag is a waste product. To reduce this waste more of the remaining metallics may be leached into water and ...

 · In the secondary aluminum industry (aluminum scrap recovery), about 200 kg of aluminum is produced per each ton of secondary aluminum (Seng et al., 2006). By 2020, annual global demand for aluminum will reach to about 97 million tons and almost 32% of which that equals to 31 million tons is expected to be supplied from scrap recycling ( Tsakiridis et al., 2013 ).

Keywords: Aluminium recycling, salt slag, coalescence, metal losses. Abstract Contaminated aluminium scraps are often recycled in Tilting Rotary Furnaces under a salt flux. The salt flux has three main functions: protect the metal surface against oxidation, promote the coalescence and remove the impurities (mainly oxides) from the metal bath. The last aim leads to an evolution of the salt ...

Origins of Aluminium Salt Slag

This salt slag is a hazardous waste which must be disposed of under controlled conditions. Historically, in Europe, aluminium salt slag was landfilled. More recently, a combination of tighter environmental regulation and high landfill costs has terminated this practice. Instead, aluminium salt slag is recycled in dedied plants such as RVA. Reprocessing is recognized across the EU as the ...
