Aluminum smelting dross problems and solutions. Dross is a surface layer on a metal melt, which has a high oxide content. 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.
An example of mechanical cleaning is the dry milling process. Cold aluminum-laden dross and other residues are processed by milling and screening to obtain a product containing at least 60 to 70 percent aluminum. Ball, rod, or hammer mills can be used to reduce oxides and nonmetallic particles to fine powders for ease of removal during screening.
