Abstract

εφεύρεση αναφέρεται σε μία μέθοδο για την κατακρήμνιση νικελίου από ένα υδατικό του διάλυμα υπό τη μορφή μεταλλικής κόνεως με τη χρήση υδρογόνου. Το υδατικό διάλυμα το οποίο περιέχει ενώσεις του νικελίου εξουδετερώνεται αρχικά με μία ένωση αλκαλικής γαίας ή αλκαλίου έτσι ώστε το νικέλιο να κατακρημνίζεται ως υδροξείδιο του νικελίου ή ως αλκαλικό άλας και εν συνεχεία πραγματοποιείται αναγωγή παρουσία ενός καταλύτη υπό τη μορφή ιόντων υπό ατμοσφαιρικές ή γειτονικές των ατμοσφαιρικών συνθήκες, κατά προτίμηση ως συνεχής διαδικασία. ΰ
