Applications of bauxite residue: A minireview Ajay S ...

Bauxite residue is the waste generated during alumina production by Bayer's process. The amount of bauxite residue (40–50 wt%) generated depends on the quality of bauxite ore used for the processing. High alkalinity and high caustic content in bauxite residue causes environmental risk for fertile soil and ground water contamination.

Bauxite Research Papers

Bauxite produces 60120 million tons of toxic red mud annually during its processing to alumina. Thus, in this work, the modeling of the bauxite processing process to reduce quantity of red mud produced and with low alumina content was envisaged. Bauxite from MinimMartap was processed by adapting the Bayer process under laboratory conditions.
