Metal recovery from aluminium dross
The ElectroStatic Separator recovered a further 6 % of aluminium. The tests concluded that approximately 15 % of aluminum could be recovered from the dross using a combination of the three separators. Production-scale equipment. The production-scale equipment was sized to handle approximately 3 t/h of 1.5 to 20 mm aluminium dross.

Utilization of aluminium dross as asphalt filler
Géber Róbert. Aluminum dross is a recyclable by-product of the aluminum manufacturing process. Since the use of aluminum alloys increased in large quantities, which cause a significant amount of aluminum dross produced, therefore, the need for alternative solutions are also increased. The goal of this study is to investigate the utilization ...

The hot aluminum dross recycling (HDR) system
Abstract. The usual methods of processing aluminum dross involve first cooling the dross to room temperature by means such as rotary drum coolers, stationary inert gas coolers or floor spreading, with varying effectiveness. The remaining metal is then recovered by reheating the raw dross (or a milled concentrate) with salt flux in a rotary ...

Aluminum Slag: Problems and Solutions
Slag is formed on the surface of melts as a result of interaction with air gases, primarily, with oxygen. Slag is a physical mixture of oxides and other solid compounds, as well as molten metal, which is inside them. Dross, which forms on the surface of the aluminum melt, is an inevitable by-product. Slag is " on molten metal" [1].
