Efficient dealkalization of red mud and recovery of valuable metals by a sulfur-oxidizing bacterium - Frontiers

Red mud (RM) is a highly alkaline polymetallic waste generated via the Bayer process during alumina production. It contains metals that are critical for a sustainable development of modern society. Due to a shortage of global resources of many metals, efficient large-scale processing of RM has been receiving increasing attention from both researchers and industry. This study investigated the

G¡ä for the hydrogel with 10% red mud was 50 times higher than G¡ä for the polyacrylamide hydrogel. This increase is mainly attributed to the physical interactions that are present between the clay and the polymer, which, by forming reversible crosslinking points, act as energy dissipators when the material is subjected to stress, thus preventing it from failing.

Nonionic polyacrylamide was selected as anti-scouring admixture to eliminate the influence of different polymer electrical properties (Lu et al. 2022). The molecular weight of PAM is more than 10 million Daltons, and its main chain is connected with a C=O bond and an amino functional group as a branch chain structure, as shown in Fig. 2 .

Nonionic polyacrylamide has a strong hydrophilic character, greater than other nonionic, water-soluble polymers. Despite being described as nonionic synthetic polyacrylamides obtained as a result of polymerization or copolymerization of acrylamides, often contain in their macromolecules about 1¨C3% of anionic groups [ 4 ].
