Abstract
Alumina-containing dust is agglomerated into granules by mixing the dust with an organic binder to form a mixture; feeding the mixture into a rotating drum; adding water to the mixture while the drum is rotating; stirring the mixture with a rotor hastening agglomeration of the dust particles into granules; collecting moist granules from an open end of the drum; and drying the moist granules. Granules produced by the process are suitable feedstock material for production of aluminum by electrolysis of alumina in a cell containing a molten salt bath, anodes, and a cathode.
