Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes.

The older and more traditional of the two, blast furnaces can be traced as far back as ancient China (on a smaller scale). Modern blast furnaces use coke, or purified coal, to melt iron ore and create pig iron. Oxygen is then injected into the furnace, to reduce the carbon content of the steel and remove impurities.
