Jarosite residues generated during zinc hydrometallurgy may retain valuable metals such as silver within complex and poorly accessible mineral phases. In this study, hydrated reline, a choline chloride–urea natural deep eutectic solvent (NADES), was evaluated as an alternative leaching medium for silver recovery from an industrial jarosite residue. Reline/water mixtures containing 10, 20, and 30 wt.% water (RE9010, RE8020, and RE7030, respectively) were investigated to determine the influence of solvent hydration and temperature (25–80 °C) on silver extraction. Mineralogical characterization by XRD, SEM–EDS, and automated TIMA analysis revealed a heterogeneous residue in which silver-bearing phases are associated with complex mineral assemblages, potentially limiting their accessibility during leaching. Among the evaluated systems, RE9010 consistently exhibited the highest silver recovery.
