R&D Around Driving Value from Red Mud Increases

Red mud is a byproduct of aluminum production, in which alumina is extracted from bauxite ore via the Bayer process. Unfortunately, for each ton of aluminum produced, around 1-2 tons of red mud are also produced, creating a massive amount of industrial waste to manage. This red mud, or bauxite residue, represents a significant challenge to the industry due to its highly caustic nature and the
