“…Equally important, the generated metal-sulfide sludge has much better dewaterability characteristics, generating a more concentrated metal sulfide product reducing the cost for transportation and further processing of the produced metal concentrates. Finally, beyond these operational benefits in terms of metal removal and lower sludge volumes, sulfide precipitates can be directly recycled within the process, as most metal refineries treat metal sulfide ores [21].…”

“…There is also a growing interest in metal recovery from various industrial wastewaters, especially mining and metal processing wastewaters (section 2.3.4). This has mainly been explored through a combination of biological, membrane (filtration), and precipitation processes, with particular focus on the biological sulfate-reduction process (Gómez & Lens, 2017;Huisman et al, 2006;Kumar & Pakshirajan, 2021;Weijma et al, 2002). This process uses microorganisms to reduce sulfate to sulfide, producing sulfidic metal precipitates along the way, and has currently been applied at full scale to recover metals such as copper (Cu), nickel (Ni), and Zinc (Zn) (Gómez & Lens, 2017).…”

Further processes that have been implemented or are being developed for metal recovery include: hybrid membrane technologies, electrocoagulation, ion exchange, and solvent extraction (Brooks, 2018;Parga et al, 2009).…”
