dc.description.abstractIn this study, aluminium dross undergoes a hydrometallurgical recycling process. Various chemical reagents are employed to treat the aluminium dross, facilitating the maximum extraction of aluminium content from the dross into leach liquor. The hydrometallurgical route ensures efficient aluminium leaching, forming a solution rich in Al, used as a precursor/raw material for valuable material generation. α-alumina is obtained by leaching dross with alkalis at 323 K for 3 h and precipitating with acids followed by a calcination process at 1,473 K for 3 h. The parameters are optimized and multiple trials are done to ensure the reproducibility of the results. Morphological and topographical studies of the synthesized products are done by XRD and SEM-EDS characterizations. TGA analysis of the samples were also conducted. This work enables to recycling of aluminium dross and converts it into a valuable product which has high demand in refractory and high-temperature applications. By converting aluminium dross into a resource with intrinsic value, this process significantly mitigates environmental impact, aligning seamlessly with the principles of a sustainable and circular economy. In doing so, it exemplifies a proactive approach towards resource conservation, waste reduction, and the responsible utilization of materials within industrial processes.eng
