Current Status of an Industrial Waste: Red Mud an Overview

Engineering, Mining Engineering
Abstract: - Red mud is a solid residue Produced during the alumina production by the bayer process from bauxite. The red mud generated by this process is highly alkaline with pH usually ranging from 10 to 13. Due to its hazardous corrosive nature its posing a very serious and alarming environmental problem. Globally there are approximately 90 million tonnes of red mud being produced every year. More than 4 million tons of red mud is generated annually in India only. The amount of the red mud generated per ton of the alumina processed, varies greatly with the type of the bauxite ore used. Due to its hazardous nature it is a great challange to researcher to develop new methods for the application of red mud. Various research work going on for the storage, disposal and utilization of the red ...
