Taconite Wikipedia

Taconite (IPA: ['tækənaɪt]) is a variety of iron formation, an iron-bearing (over 15% iron) sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate.The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) son of Newton Horace Winchell, the Minnesota State Geologist during their pioneering investigations of the Precambrian Biwabikget price

Commercialization of Taconite MNopedia

Though taconite was identified as an iron-bearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasn’t until then that it was profitably extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves were diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changingget price
