Abstract

A method for treating hot skim material to separate, recover, and prepare for use both aluminum and non-aluminous constituents contained in the hot skim materials involves a centrifuge having a rotatable bowl to receive a charge of skim material. The centrifuge then both consolidates the non-aluminous constituents thereof into a semi-porous cake and separates and discharges molten aluminum as the bowl is rotated. The semi-porous cake is cooled and found to be friable. Thereafter, the friable cake is crushed and screened to be used as a foaming and extending agent.
