Taconite is a flint-like type of rock containing low-grade iron ore. Vast reserves of taconite, with iron concentrations of 30-50%, were discovered in 1870 near present-day Babbitt, on the Mesabi Iron Range. However these deposits were passed over in favor of mining existing high grade iron ore formations, because extracting the pure iron from ...
