Calcination. Digestion . In this step the bauxite slurry is pumped from the holding tanks to the autoclaves (digester vessels) where it is mixed with hot concentrated caustic soda liquor. The digestion temperature and pressure depend on the mineralogical composition of the bauxite. Most bauxitic ores are composed of gibbsite (Al(OH) 3. or AlO
*Note: The term “calcination” is often loosely used to refer to thermal treatment techniques that may or may not meet the technical definition. Equipment Used. Rotary kilns are used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or indirect-fired type.
