The Bayer processBayer process, commercialized in the late 1800s, remains the predominant method for aluminaAlumina production, accounting for over 95% of global output. Approximately 1 to 1.5 tons of bauxite residueBauxite residue is generated for each ton of aluminaAlumina produced, leading to a global stockpile estimated at 3 to 4 billion tons stored in containment dams. The current recyclingRecycling rate of bauxite residueBauxite residue is less than 5%, with the majority having applications in the cement industry. This work presents a hydrometallurgical process for recovering high-purity magnetiteMagnetite from bauxite residueBauxite residue. Large-scale laboratory trials (20 L) were conducted to extract high-purity magnetiteMagnetite, along with aluminaAlumina, silicaSilica and calcium carbonateCalcium carbonate as side products. The potential for recovery of rare earth elements (scandiumScandium) within the process flowsheet was also evaluated.
