Iron mines of the era exploited the "natural" (soft) iron-rich ores in a 15 kilometer-long stretch in the central portion of the range straddling the Michigan-Wisconsin state line. These mines were mainly of the underground shaft type, which were among the deepest iron mines in the country. Due to these characteristics, and the greater ...
US iron ore made up 2.5 percent of the total mined worldwide in 2015. Employment as of 2014 was 5,750 in iron mines and iron ore treatment plants. [3] US iron ore mining is dominated by the Precambrian banded iron formation deposits around Lake Superior, in Minnesota and Michigan; such deposits were also formerly mined in Wisconsin. For the ...

It was the nation's largest supplier of iron ore by the 1890s, and production continued to a peak in the 1920s but sharply declined shortly afterward. The last copper mine closed in 1995, although the majority of mines had closed decades before. Some iron mining continues near Marquette. [4] The Eagle Mine, a nickel-copper mine, opened in 2014. [6]
Cleveland-Cliffs manages and operates four iron ore mines in Minnesota and two mines in Michigan, one of which, the Empire Mine, has been indefinitely idled. [3] These mines produce various grades of iron ore pellets, including standard and fluxed, for use in blast furnaces as part of the steelmaking process as well as Direct Reduced (DR) grade pellets for use in direct reduced iron (DRI ...
Ironwood is located within the now inactive Gogebic Iron Range. Iron ore was found in the area in the 1870s. The arrival of the railroad in the mid-1880s gave an impetus to more extensive development of the area's ore deposits. Several mines, such as the Norrie, Aurora, Ashland, Newport, and Pabst, were opened in Ironwood.
