Abstract
An improved method for processing aluminum dross containing fluxing salt to provide a fired inorganic or ceramic product wherein said dross is processed to remove fluxing salts therefrom, and wherein a non-metallic product is recovered. The improved process comprises providing a body of the non-metallic product in an aqueous slurry, a major portion of the body comprised of Al.sub.2 O.sub.3 and minor portions of said body comprised of SiO.sub.2 and MgO. The composition of the slurry is adjusted by adding one of Al.sub.2 O.sub.3 and SiO.sub.2 in an amount sufficient to form the fired inorganic product on heating. The slurry is heated to a temperature sufficiently high to fire the slurry and produce the fired inorganic product.
