A plant for producing pig iron and / or sponge iron has a direct reduction shaft furnace (1) for lumpy iron ore, a melter gasifier (3), a melt-down gasifier (3) with the shaft furnace (1) connecting line (4) for a reducing gas, the shaft furnace (1) with the melter gasifier (3) connecting the conveying line (13) formed for the shaft furnace (1) reduction product, from the shaft furnace (1) outgoing top gas discharge duct (14), in the melter gasifier (3) opening out leads ( 5, 6, 7) for oxygen-containing gases and carbon carriers and the meltdown vessel (3) provided for tapping (11) for pig iron and slag. In order to process not only lumpy ore, but also fine ore energy and product optimized is the system by at least one fluidized bed reactor (15, 16) to receive fine ore, a reducing-gas feed (21) to this fluidized bed reactor (15, 16), an exhaust deflection (22) from the fluidized bed reactor (15) and a discharge device (34) for the fluidized bed reactor (15, 16) in the reduction product formed, in the melter gasifier (3) reduced a conveyor for introducing the in the fluidized bed reactor (15, 16) , preferably subsequently briquetted reduction product opens.
