Cover Story: The increasing use of electronic devices has also led to an increase in the demand for many metals, of which gallium is especially important due to its wide range of applications. For this reason, gallium has been incorporated into the critical raw materials list. In this context, it is crucial to seek alternative sources of gallium, with the Waste from Electrical and Electronic Equipment (WEEE) and Bayer liquor from the alumina process being reliable alternatives. These residues can be digested to generate aqueous streams, from which gallium can be recovered with several processes, such as adsorption. Adsorption does not allow a direct recovery of gallium, but it allows its preconcentration so that further recovery treatments are economically feasible. In this study, we compare two potential candidate adsorbents for gallium recovery. View this paper
