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 opening up of a new mine in Germany's Erzgebirge (Ore Mountains) in late 2013 marked a milestone for German mining, continuing the tradition in this region, following decades of stasis. The reasons for the extraction of fluorspar and baryte are closely tied to steadily rising raw material prices on the world market.
