Sponge Iron

Sponge iron is produced by low-temperature reduction of iron ore in a rotary furnace, shaft furnace, or reactor.

Smelting sponge iron in electric arc furnace

The HYBRIT process involves removing the oxygen from the iron ore using hydrogen. The reduction occurs at a lower temperature and the result is so-called sponge iron (direct reduced iron). The sponge iron is smelted in a furnace, powered by electricity. The furnace is called an Electric Arc Furnace (EAF).
