Direct reduced iron process
The reduction gases only dissolve oxygen from the iron ores. This causes the iron ores to crack on the surface. The appearance resembles a porous sponge, which is why the deoxidized and thus strongly ferrous iron ore is also called sponge iron. Sponge iron is a highly ferrous ore from the direct reduced iron process!
