AlCl\u2083 kabarc\u0131klar\u0131 erimi\u015f al\u00fcminyumdan ge\u00e7erken al\u00fcmina par\u00e7ac\u0131klar\u0131, metal flor\u00fcrler ve k\u00f6m\u00fcr \u00fczerinde adsorbe olurlar. Kabarc\u0131klar, kat\u0131 fazla birlikte yukar\u0131 y\u00fckselir ve y\u00fczeyde gev\u015fek gri bir tabaka olu\u015fturur; bu tabaka daha sonra uzakla\u015ft\u0131r\u0131l\u0131r. Ayr\u0131ca, klorun ge\u00e7i\u015fi, metalden gazlar\u0131n uzakla\u015ft\u0131r\u0131lmas\u0131na yard\u0131mc\u0131 olur. Ar\u0131tma i\u015fleminden sonra Al i\u00e7eri\u011fi ,5 \u2013 99,81'dir. Bu, \u00e7o\u011fu t\u00fcketici i\u00e7in uygundur; ancak bazen daha saf al\u00fcminyum gerekti\u011finde, al\u00fcminyum, b\u00f6lgeli eritme veya alt ba\u011flant\u0131lar yoluyla dam\u0131tma y\u00f6ntemleriyle daha derin bir ar\u0131tma i\u015flemine tabi tutulur.<\/p>\n
