ABSTRACT:
Apparatus and method for concentrating metallic aluminum from dross comprising a system in which dross is repeatedly and continuously passed through an impact type mill to mill the material and to enable the metallic aluminum concentrates to be separated from the non-metallic components of the dross. A portion of the milled material is continuously diverted by a percent divider to a screening zone where it is classified according to particle size. Through-put devices regulate the average number of passes that material is circulated through the mill in accordance with particle size to obtain a product of relatively high aluminum concentration and a by-product of a relatively low aluminum content.
