The highly alkaline red mud generated from alumina refining has long been seen as a challenging waste issue for the aluminum industry. However, with innovative thinking and technologies, the potential exists to turn this polluting residue into useful products and environmental solutions. Utilization Avenues for Red Mud Although managing the large quantities of red mud …
The caustic red colored waste produced during alumina refining has been responsible for some of the worst environmental disasters in recent decades. Called red mud or bauxite residue, this highly alkaline byproduct has caused severe pollution and loss of life when spilled into surrounding areas due to breaches in holding ponds and reservoirs. Examining some …
Red mud is a highly alkaline waste generated during the Bayer process of refining bauxite ore into alumina, the raw material for aluminum production. As global aluminum production increases to meet demands from construction, transportation and other sectors, the scale of red mud waste generated each year also grows. Recent estimates indicate that more than …
