PROCESS DESCRIPTION: ALUMINA REFINING The bauxite ore contains aluminum trihydrate (Al(OH)3). The reaction is firstly driven in the sodium aluminate (NaAlO2) direction by the addition of caustic soda (NaOH) to bauxite. Bauxite residues are then removed, leaving the process liquid, termed "green liquor."
Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry process. In wet milling, water or alcohol commonly is used as the milling liquid.
