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.

Direct Reduced Iron and its Production Processes – …
Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.
