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.

Iron Ore Mining Essentials: Key to Steel Production
Once the deposit of iron ore is feasible, the mining process is moved to digging the ore out from the earth. The most widely used technique is open-pit mining, which involves drilling and blasting the surface rock and soil to get to the ore deposit beneath it in states like Minnesota and Michigan, around the area of Lake Superior.
