application of bauxite

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
