Abstract
έθοδος μετατροπής ακαθάρτου αλουμίνας εις εν προϊόν πολύ υψηλής καθαρότητας, συνιστάμενη εις το να προσβάλωμεν ακάθαρτο αλουμίνα δι' ενός διαλύματος θειικού οξέος, να κατεργασθώμεν το ληφθέν θειικό διάλυμα δι' υδροχλωρικού οξέος ίνα καταβυθίσωμεν τοένυδρο χλωριούχο αλουμίνιον, να αποχωρίσωμεν δια διηθήσεως την χλωριούχο ταύτη ένωσιν των ακαθαρσιών, παραμενουσών εν διαλύσει και ακολούθως να διασπάσωμεν δια θερμότητας τον υδρίτην της χλωριούχου ενώσεως εις καθαρά αλουμίνα και υδροχλωρικό οξύ.
