Identification and Description of Mineral Processing ...

To produce dry bauxite, most of the free moisture is removed by heating crude bauxite in rotary drying kilns. Calcined bauxite is produced by heating bauxite to reduce total volatile matter, including chemically combined water, to less than one percent. Approximately two tons of crude ore is required to produce one ton of calcined bauxite.
