In contrast, pig iron production involves high temperatures and a blast furnace. 14. Sponge iron is considered more environmentally friendly due to its lower energy requirements and lower carbon emissions compared to pig iron production, which is energy-intensive and has higher carbon emissions. 13. The quality of sponge iron, with …

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! In order to …
