Blast furnace process - tec-science
The unmelted iron ores still contain non-reduced iron oxides. An unfavourable accumulation of ores at the contact points can also make gas flow difficult and thus leave non-reduced iron ore behind. At the latest, however, when the melting process occurs in the deeper and hotter zones of the blast furnace, iron ores can be almost completely reduced.

What happens to iron ore in a blast furnace? - R4 DN
Iron ore, coking coal, and limestone are added into the top of the blast furnace while heated air is blown into the bottom of the furnace to drive the combustion process. The combustion of iron ore with other materials in the blast furnace produces molten pig iron, which is then converted to steel.
What happens to iron ore in a blast furnace ...
What happens to iron ore in a blast furnace? The blast furnace Iron ores such as haematite contain iron (III) oxide, Fe 2O 3. The oxygen must be removed from the iron (III) oxide in order to leave the iron behind. In this reaction, the iron (III) oxide is reduced to iron, and the carbon is oxidised to carbon dioxide.
