METHOD OF RECYCLING ALUMINUM DROSS
An improved method is disclosed for processing aluminum dross containing fluxing salts to provide a fired inorganic or ceramic product wherein the dross is processed to remove the fluxing salts therefrom, and a non-metallic product is recovered. The dross is processed through a crusher (10) and the reduced fragments (10(a)) are classified by passing over a screen (12). A portion of the classified material is fed into a digester (14) and a wet screen (16) is used to screen the digested material. A portion of the screened material is sent to a dryer (18), passed through a dry screen (20) and fed to a furnace (22). The improved process comprises mixing the non-metallic product with water and alkali matrials to form a slurry and adding acid to neutralize the slurry. The slurry is adjusted by adding one of silica and alumina and the slurry is heated to form a fired product (fig. 2).
