Sustainable recycling of spent aluminium electrolyte for AlF <sub>3</sub> and efficient fluoride recovery via an integrated pyro-hydrometallurgical process
ions.to form hydroxyaluminum fluoride. Characterization via XRD, XRF, and SEM confirmed the superior phase purity and uniform morphology of the products. This developed process offers a highly efficient, environmentally benign solution for SAE valorization, contributing substantially to resource recovery and the circular economy within the aluminium sector.
