An attempt was also made in the present investigation to enrich the titanium dioxide content in red mud by reversing the steps followed above, that is roasting followed by leaching. In this method, the fractional enrichment of titanium dioxide is lower. 3.7. ConclusionsA new method for enrichment of titanium dioxide in red mud is identified.

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.

Red mud is a polymetallic waste generated during Bayer's process of alumina production. High alkalinity (pH > 11), multiple elements, and micron-sized particles make red mud recycling energy-intensive and challenging. The following work presents a hydrometallurgical flowsheet for separation of different red mud elements and recovery …

Recovery of titanium and vanadium from red mud. Titanium is mainly present as titanium dioxide (TiO 2). It is a popular photocatalyst and applied in the manufacture of white pigments. The concentration of anatase or rutile titanium in the red mud varies between 2.5 wt.% and 22.6 wt.% (Gräfe et al., 2011), as shown in Table 1.
