Additional information
In the blast-furnace process, direct reduction — in contrast to indirect reduction — means the reduction of ferrous oxide by carbon with the formation of CO. The terms “direct reduction of iron,” “direct production of iron,” “cokeless metallurgy,” or “non-blast-furnace metallurgy” are used in the literature to denote new methods for the metallurgical conversion of iron ore to iron.
