Germaniy (Ge) — yarimo‘tkazgichlar, infraqizil optika va fotovoltaika uchun strategik ahamiyatga ega kritik element bo‘lib, uning ta’minoti yuqori darajada Xitoyga bog‘liq va so‘nggi yillarda eksport cheklovlari hamda narxning keskin oshishi tufayli alternativ manbalarga qiziqish ortgan. Ushbu maqolada germaniyni ko‘mir yonish va gazlashtirish kullari (ikkilamchi texnogen
xomashyo) leachatlaridan selektiv ajratib olishning gidrometallurgik usullari — ishqorlash (leaching), erituvchi bilan ekstraksiya (solvent extraction), ion almashinuvi, adsorbsiya, cho‘ktirish, ion flotatsiyasi va membrana jarayonlari — qiyosiy tahlil qilindi.
