The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

As societies progressed, humans began to extract iron from terrestrial sources, marking the transition from the use of meteoric iron to smelting iron ore. One of the earliest known methods of iron smelting was the bloomery process. This ancient technique, dating as far back as 1200 BCE, involved heating iron ore in a furnace with charcoal.
