•    Description:  The largest waste by-product generated in the Bayer bauxite refining process is bauxite residue, commonly called red mud. An enormous quantity of caustic red mud is generated worldwide every year, posing a very serious and alarming environmental and safety problem. This article provides a valuable look at bauxite refining and red mud generation from the Bayer Process, along with a look at methods for managing red mud, such as lagooning, dry stacking, and dry disposal, as well as the utilization of the by-product in other industries. Also addressed are processes for neutralizing the high alkalinity of red mud, including sea water neutralization, acid neutralization, carbonation, geosequestration, flue gas neutralization, and calcification-carbonation.
