Making iron & steel
Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process also produces two ...

DRI production | International Iron Metallics Association
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.
Iron processing | Definition, History, Steps, Uses, & Facts
The blast furnace appeared in Europe in the 15th century when it was realized that cast iron could be used to make one-piece guns with good pressure-retaining properties, but whether its introduction was due to Chinese influence or was an independent development is unknown. At first, the differences between a blast furnace and a Stückofen were slight.

The Blast Furnace: 800 Years of Technology Improvement
The modern world uses shocking amounts of steel. The input requirements for 16th century blast furnaces were large. Though fuel consumption had fallen to roughly the level of the bloomery furnace (initially it used much more fuel than a bloomery), producing a ton of pig iron still required roughly 4.5-5 tons of charcoal, and 5.5-7 tons of iron ore.
