A method for the direct reduction of metal oxides with carbon. According to the method, pellets are formed containing a mixture of metal oxides having sequential reduction potentials when heated in the presence of carbon and an amount of carbon sufficient to reduce more easily reduced of the metal oxides yet insufficient to reduce all of the metal oxides. The pellets are heated to a temperature at least sufficient to reduce the more easily reduced metal oxides to produce direct reduction metal while removing sufficient of the carbon in the form of oxides of carbon during the reduction to avoid a subsequent decarburization step in further processing of the direct reduction metal. |
