The flash joule heating process effectively removes iron and heavy metals from bauxite residues, suggesting improved recycling methods.

Over 96% of iron can be removed from bauxite residues using flash joule heating and chlorination.
The process retains about 99% of aluminum in the bauxite residues, ensuring resource efficiency.
Life-cycle assessment highlights lower emissions and costs compared to traditional aluminum extraction methods.
The valorization of bauxite residues into high-performing ceramics signifies a sustainable recycling opportunity.

Liu et al. (2025) studied this question.
