Properties and Assessment of Applications of Red Mud ...
Published research studies on characterization and utilization of red mud (RM) are very disjointed, and characterization of RM for valorization is considered inadequate. To date, compilation and detail discussion on physical, chemical, mineralogical and geotechnical characteristics of RMs of different origin in a comprehensive way have not been reported in the literature.
