Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel — 98% of the mined iron ore is used to make steel. [2] In 2011 the Financial Times quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity ...
The high demand for iron necessitates continuous mining and processing, which generates a large amount of solid and liquid waste. Iron ore tailings are leftover materials that are released once mineral processing is complete. [10] This waste includes large amounts of iron and manganese oxides in addition to high pH values. [11]
Iron-rich sedimentary rocks have economic uses as iron ores. Iron deposits have been located on all major continents with the exception of Antarctica. They are a major source of iron and are mined for commercial use. [1] The main iron ores are from the oxide group consisting of hematite, goethite, and magnetite.
The lengthy epidemiological study of Minnesota iron miners concluded in December 2014 that those working 30 years in the iron mines and living to be 80 years old had a lifetime chance of having a mesothelioma of 3.33 cases per thousand such workers, more than double the background rate of 1.44 cases per thousand people living to 80 years old.

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 ...

The term "minette" came from French miners. It is a diminutive form of "la mine", and might be translated as "little mine, little colliery" or "little vein", referring to its relatively poor iron content of between 28% and 34%. [2] In other uses, "minette" is also an archaic rock term used to locally describe a particular type of lamprophyre. [2]
