Abstract
(See also chem. Abstr. 86:143,538T) aluminum is recovered from waste aluminum materials including beverage can scrap and dross skimmed from aluminum melts in furnaces, crucibles, or ladles, by heating the scrap or dross at 700 deg-800 deg c under an ar atmosphere with agitation to collect metallic material at the bottom without the conventional addition of any salt flux, leaving a salt- free porous oxide mass that can be disposed of a nonpolluting landfill, or used for thermal insulation in hot tops of molds for large steel ingots.
