Recovery of sodium from bauxite residue by pressure filtration and
Introduction. The production of alumina from bauxite ores by the Bayer process generates bauxite residue as the main waste fraction. The amount of bauxite residue (red mud) generated while producing 1 t of alumina is typically about 1–2 t, and the residue inventory is, according to numbers from the year 2007, increasing by quality of the Bauxite ore. The process in use is Crushing, Elutriation (Washing) and. Separation of Fines.
