Abrégé
The disclosed technology includes a method for producing ultrafine alumina from salt slag waste generated in aluminum recycling useful in the manufacture of durable ceramic products; a system for recovering alumina from salt slag waste; a method and systems for recovering salts, aluminum and alumina from salt slag waste; and a method and systems of capturing ammonia in a process recovering salts, aluminum and alumina from salt slag waste. The methods and systems provided crush the dry particles of the salt slag waste, scrub the slag with water, and with steam and by means of a vented alumina press, dewater the scrubbed slag particles. In some methods and systems of the disclosed technology, the particles of the pressed alumina cake are further reduced. In some methods and systems, the salt in the salt effluent is crystalized. In some methods and systems of the disclosed technology, the ammonia is contained and captured.
