Red Mud: A Wealth of Opportunity for Metal Recovery

While red mud is a major problem, it also contains a variety of metals that could be extracted. Some estimates say that red mud can contain as much as 64% Iron oxide (Fe 2 O 3), 43% aluminum oxide (Al 2 O 3), and 24% titanium dioxide (TiO 2),² though it’s important to note that the composition of red mud varies significantly across sources.
