The molten iron has a dissolved carbon content of approximately 3.6% as well as some silicon, manganese, vanadium, and titanium. Slag, which floats on top of the iron, has the function of removing impurities from the iron and its chemical composition and temperature to a large extent determine the chemistry and hence quality of the iron.

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.
