A process for the agglomeration of powder or dust of alumina containing material (herein referred to as "alumina powder"), wherein an aqueous slurry of the alumina powder is formed, the slurry containing a sufficient quantity of an inorganic binder comprising a polymer form of a hydroxy salt of aluminium. The slurry is subjected to a spray drying operation to form agglomerated granules of the alumina powder, and the granules then are calcined at an elevated temperature for their consolidation. The alumina containing material comprises Al2O3.nH2O, wherein n is in the range of from 0 to 3.
