Exploitation and utilization of O2 materials from red mud

Red Mud is a dust-like and high alkalinity waste material produced during the production of alumina from Bauxite ore by Bayer Process. Nearly 1 – 2.5 tons of Red mud, which consists of various oxides are produced per ton of alumina. The current practice is the disposal into long-term-storage sites, which is a major environmental problem throughout the world. Now the question comes: why to throw this valuable material as industrial waste and create environmental pollution instead of reusing it. This paper examines various possibilities of exploitation and utilization of Red Mud.Red Mud is a dust-like and high alkalinity waste material produced during the production of alumina from Bauxite ore by Bayer Process.
