But on the Mesabi and Cuyuna Ranges, iron mining operations evolved into enormous open pit mines, where steamshovels and other industrial machines could remove massive amounts of ore. "Large-scale commercial production of magnetite taconite ore on the Mesabi Range started in 1956 at the Peter Mitchell Mine near Babbitt, Minnesota." [2]

Open pit mining started at the Rowe mine in 1912. In addition to the iron, the ore was rich in manganese, which was useful during World War I, with 32 mines operating. [1]: 6 At the height of the mining, the Cuyuna Range was the location of the worst mining disaster in Minnesota, the Milford Mine disaster. [3]
The Seven Iron Men, also known as the Merritt brothers, were iron-ore pioneers in the Mesabi Range in northeastern Minnesota and the creation of the city that is now known as Mountain Iron.
