Abstract

A method of electrolytic reduction of a feedstock comprising oxygen and a first metal comprises the steps of, arranging the feedstock in contact with a cathode and a molten salt within an electrolysis cell, arranging an anode in contact with the molten salt within the electrolysis cell, the anode comprising a molten second metal and applying a potential between the anode and the cathode such that oxygen is removed from the feedstock to form a reduced feedstock. The oxygen removed from the feedstock reacts with the molten second metal to form an oxide comprising the second metal. The second metal is aluminium. The reduced feedstock may comprise a proportion of aluminium.
