Iron Mining - Encyclopedia of Wisconsin Environmental History

Iron mining refers to the excavation of iron ore, most of which is used as a key component in the production of steel. Most of the iron ore in Wisconsin can either be classified as taconite (25-35% iron) or high-grade ore (50-70% iron). While Wisconsin is known as an agricultural state, it started as a mining state in the mid-19th century.

Iron Ore Mining Techniques Metal Extraction

The iron ore, coke and limestone are crushed into small round pieces and mixed and put on a hopper which controls the input. The most common ores of iron are hematite Fe 2 O 3, and magnetite, Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke.
