FAQ: How is iron produced in the blast furnace? Kitchen
2021-10-29 Iron is produced by reduction of iron ore, which is often a mixture of oxides, using carbon, carbon monoxide, and hydrogen. Most ores contain more than 60% iron and are used in their mineral state in a blast furnace. Ore containing less than this is first crushed and ground into a powder and concentrated by flotation.
