Review on treatment and utilization of bauxite residues in Review of Bauxite Residue Alkalinity and Associated Chemistry

Recycling Bauxite residue red mud is a solid waste produced in the process of alumina extraction from bauxite More than 70 million tons of bauxite residue is generated annually Presently it is stored on land or in the ocean near alumina reļ¬neri However its high alkalinity is a potential pollution to water land and air of close proximity Meanwhile high costs are associated with the alkaline waters to ground and surface waters are not well documented in the literature Support for a review of the sealants and research on their reactivities under accelerated test conditions would be appropriate The establishment of techniques for creating self managing sustainable ecosystems from bauxite residue impoundments is the most realistic solution to the large and increasing
