The present invention relates to a method for producing a feed material for molten metal production, the method comprising the steps of heating a mixture containing a metal oxide-containing material and biomass to carbonize the biomass in the mixture in a heating furnace substantially isolated from oxygen; charging the mixture in a reducing furnace; reducing the metal oxide-containing material contained in the mixture in the reducing furnace; and melting the mixture by heating in the reducing furnace after the step of reducing the metal oxide-containing material contained in the mixture in the reducing furnace.
