A method and apparatus for producing molten metal from powder state ore through smelting process to be performed in a shaft furnace, utilized the reducing material having grain size greater than that n-times of the gas blow velocity corresponding grain size to charge rom the top of a shaft furnace for forming fluidized bed at the upper section of the furnace and a reducing material filled section below the fluidized bed. The method and apparatus for smelting the powder state ore also takes the reducing material having smaller grain size to be blown into the furnace through tuyeres.
