In this study, the feasibility of producing electrolytic iron from red muds in a strongly alkaline medium at 110 °C was studied. The red mud samples from a French industry were characterized by various techniques (ICP-AES, SEM, XRD) to determine their chemical and mineralogical compositions. The main phase in the red mud investigated was hematite (α-FeO).

- This study focuses on creating synthetic copper-substituted hydroxyapatite (Cu-Hap) to effectively immobilize uranium from solutions and real mining waters through a co-precipitation method.* -
- The research found that Cu can be incorporated into Cu-Hap up to a limit of x ≤1.59, and different copper content influences the mechanisms of uranium removal when exposed to varying pH and chemical conditions.* -
- The results highlight that Cu-Hap enhances the precipitation of meta-torbernite as the main uranium removal mechanism, particularly in water with a pH greater than 6.7, where carbonate uranium species are prevalent.*
