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.
