Around 30 million tonnes of bauxite residues (red muds), resulting from aluminium extraction via Bayer process, are stored at the Porto Vesme disposal site in southern Sardinia, Italy. The primary crystalline components these include iron oxides, hydroxides, titanium silicates, carbonates, and halides, along with several minor phases. Lanthanide-rich phosphate minerals occasionally detected. Na-aluminosilicates results desilication, while hydroxides oxyhydroxides residual alumina minerals,...
This research explores the major element control on distribution of critical metals (CM) in red muds (RM), residues Bayer process developed bauxite ore, sampled at Porto Vesme disposal site, Sardinia, Italy. RM represent an environmental challenge due to their high alkalinity and storage issues. The relationships between elements CM were assessed by Compositional Data Analysis (CoDa).X-ray powder diffraction (XRPD) revealed predominant minerals including hematite, gibbsite, boehmite,...
