the mineralogy of bauxite for producing smelter grade alumina
Refractory grade bauxites have a high alumina content and a very low alkali content with low impurities (iron oxide and titania specifically), ensuring stable temperature strength. LKAB Minerals offer RASC Bauxite as standard with the following properties: RASC Bauxite. RASC (refractory Aggregate Super Calcined) bauxite is rotary calcined.
