ABSTRACT:
The prevent invention provides a method for producing a feed material for molten metal production and a method for producing a molten metal capable of sufficiently carbonizing biomass and effectively using carbonized biomass as a reducing agent. In the method for producing a feed material for molten metal production, a mixture containing an iron oxide-containing material and biomass is heated in a heating furnace substantially isolated from oxygen to carbonize the biomass in the mixture and obtain a feed material for molten metal production, or the mixture is charged in a reducing furnace to reduce the iron oxide-containing material after being heated in the heating furnace. In the method for producing a molten metal, the feed material for molten metal production obtained by the method for producing a feed material for molten metal production is charged in a melting furnace to obtain a molten metal.
