Still, the use of iron ore in the form of direct reduced iron used in EAFs may be a way around this, as already occurs in some works in the US, the analyst said. In future DRI will increasingly be produced using hydrogen rather than natural gas, Hedborg said. Blast furnaces typically burn coal to reduce iron ore to liquid pig iron.

How steelmaking may go carbon-free—by dropping its addiction …

Traditional blast furnaces use coke (coal with the volatiles cooked out) and limestone. This plus the minerals in the iron ore produce a slag. The slag carries away impurities that hydrogen reduction leaves behind. Also, hydrogen makes steel very brittle? Ever wonder why Chinese and Indian steel is mostly crap? Direct reduction with hydrogen.

Iron processing

The scarcity of coking coals for blast-furnace use and the high cost of coke ovens are two reasons for the emergence of this other alternative iron-making process. Smelting reduction employs two units: in the first, iron ore is heated and reduced by gases exiting from the second unit, which is a smelter-gasifier supplied with coal and oxygen.
