Mountain Iron in Saint Louis County, Minnesota — The American Midwest (Upper Plains)
This is Magnetic Taconite
This is magnetic TACONITE — part of Minnesota's iron formation and in many ways similar to other iron-bearing materials found in the United States and throughout the world.
Forty years of work in mining firms' laboratories and at the University of Minnesota developed methods for processing taconite's meager iron content into a competitive iron ore product. Thus, taconite processing plants represent new jobs for miners and new opportunities for those who supply or serve them.
New taconite plants were welcomed to Minnesota when her voters November 3, 1964, endorsed the principle of fair tax treatment for huge investments a taconite plant entails. The mining companies, in turn, responded immediately and again demonstrated their faith in the State by starting construction of new facilities which will expand taconite job-producing investments to exceed a billion dollars — the largest new industrial investment in the State.
One of Minnesota's new taconite plants will be located here at Mountain Iron, where Lon Merritt and his six iron men established the Mesabi’s first mine in 1890 and opened this area to development.

The Minntac Taconite Facility, owned by the United States Steel Corporation, is located near the city of Mountain Iron in central St. Louis County. Minntac began production of taconite pellets in 1967 and is the largest taconite producer in North American with an annual production of up to 15 million long tons of pellets.

3. Mesabi Range (Wikipedia). Wikipedia entry:
The Mesabi Iron Range is the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota. It has been extensively worked since 1892, and has seen a transition from high-grade direct shipping ores, to gravity concentrates, to the current industry producing exclusively iron ore (taconite) pellets.
