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-reduction degree of at least 60% in one or more pre-reduction stages. Thereafter, the method comprises completely reducing the metal oxides and melting the metal in a smelt reduction stage. The method is further characterized 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 a source of reductant.
