<p>A method of producing metals and metal alloys from metal oxides is disclosed. The method comprises the steps of partially pre-reducing the metal oxides to a pre- reducing degree of at least 60 % in one or more pie-reduction cages. Thereafter, the method comprises completely reducing the metal oxides and melting the metal in a smelt reduction stage. The method is tether characterised by carrying out at least one of the pre-reduction stages with one or more of natural gas, reformed natural gas, and partially reformed natural gas as source of reductant.</p> |
