Australian Group Develops Economical Red Mud Treatment Process

An Australian firm announced earlier this week that it has developed what it believes is the first known financially and environmentally viable and sustainable red mud waste management process. Perth’s Earth Sustaining Sciences says its Symbiotic Aquatic BioReactor process (SABR) is capable of treating the caustic by-product of alumina refining, reducing its pH from a […]

Researchers Develop Method for Extracting Valuable Material from Red Mud

One of the biggest challenges faced by the aluminium industry is disposing of “red mud,” the caustic leftover material produced when aluminium is extracted from bauxite. However, researchers from Worcester Polytechnic Institute (WPI) are working to develop a commercially-viable method for harvesting marketable metals from the substance. “We’re trying to help the environment by getting […]
