An Introduction to Steel and Steel Metallurgy

The mineral Taconite is present as sedimentary rock in places like northern Minnesota and Michigan. Taconite contains about 25% Iron (Fe) in the form of Magnetite (Fe 3 O 4) and Hematite(Fe 2 O 3). After mining and processing the concentrated iron ore pellets contain about 66% Fe with some silica (SiO 2), Lime (CaO) a small amount of other metals,
