The FINEX Process :: Total Materia Article

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
