the discharge worm 36 is supplied to the melter gasifier 10 in the region of the blow in planes of the oxygen containing gases via sleuces 39 together with the fine ore separated in the reduction cyclone 31 by aid of the n 2 injector 33 the coarser solids portion from the lower region of the reduction reactor 8 is blown or charged into the melter gasifier 10 in the region of the fine coke fluidized bed iii via sleuces 39 and by aid of the n 2 injector 9 or by means of gravity discharge the dust separated in the hot cyclone 25 primarily containing fe and c is fed to the melter gasifier 10 in the region between the fine coke fluidized bed iii and the coarse coke fluidized bed h via sleuces 39 by aid of the n 2 injector 29 and by means of an oxygen dust burner for the purpose of preheating and calcining the fluxes required for the process are charged as coarse grains preferably having grain sizes ranging between 4 and 12 7 mm via the coal path 11 and as fine grains preferably having grain sizes ranging between 2 and 6 3 mm via the fine ore path 3 for fine ores requiring longer reduction times a second as well as if required a third fluidized layer reduction reactor 8 39 including.
