Iron Ore Processing: From Extraction to Manufacturing
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.

The Blast Furnace: A Vital Tool in Climate Neutral Ore-Based
The process of transformation of iron ore to steel involves a number of steps—irrespective of the exact process route followed. It usually involves a stage of primary winning of metal from mineral ore (ironmaking—with a liquid or solid output) followed by a refining step (steelmaking—always with a liquid output).
