Molten Iron is produced directly using iron ore fines and non-coking coal rather than processing through a sinter plant and coke ovens as traditional blast furnace route. In the Finex process, iron ore fines are charged into a series of fluidized-bed reactors. The fines pass in a downward direction where they are heated and reduced to direct-reduced iron (DRI) by means of a reduction gas – derived from the gasification of the coal – that flows in the counter – current direction to the ore. The DRI fines are then hot-compacted to hot-compacted iron, transferred to a charging bin positioned above a melter gasifier where smelting take place. The tapped product, liquid hot metal, is equivalent in quality to the hot metal produced in a blast furnace ore Corex plant.
