Apstrakt
Eksponencijalni rast stanovništva doveo je do eksponencijalne potražnje za metalima, posebno za proizvodnju elektronskih uređaja, koji se na kraju svog funkcionalnog veka najčešće odlažu na deponije. Ova praksa predstavlja značajnu opasnost po životnu sredinu zbog prisustva metala u ovim odbačenim materijalima, nazvanim elektronski otpad ili e-otpad. To zahteva odgovarajuće strategije upravljanja e-otpadom, kako bi se sprečili negativni efekti na ekosistem i na ljudsko zdravlje. E-otpad sadrži vredne metale, često u koncentracijama koje čine njihovu reciklažu ekonomski isplativom. Štaviše, rastuća potražnja za metalima, vođena tehnološkim napretkom, učinila je reciklažu e-otpada ključnim elementom održivog upravljanja resursima. Ovaj rad pruža pregled hidrometalurških tehnika obrade za reciklažu vrednih metala iz otpada od električne i elektronske opreme, pre svega metala kao što su bakar, zlato i srebro. Ove metodologije koriste vodene rastvore kako bi olakšala ekstrakcija metala, predstavljajući isplativu i ekološki održivu alternativu proizvodnji metala konvencionalnim rudarenjem. Međutim, ekonomska isplativost ovih alternativnih procesa može varirati zavisno od vrste i koncentracije metala prisutnih u otpadu.
