Thin layers of iron formation occur within other rocks in northern Minnesota. The term is a contraction of "ironbearing formation," which is a rock having as much as 30 percent iron in places. Iron formation formed when ironrich particles precipitated and settled to the sea floor during quiet periods in volcanic activity. The iron formation we see today consists of thinly layered red, white ...

Minnesota Iron Iron Mining History. Minnesota has the largest deposits of iron ore in the United States and northern Minnesota has been mining iron ore for 130 years 26 years after Minnesota became a state in 1858 The majority of iron mined is used to make steel which has been used to build infrastructure appliances vehicles and so many other things that make our modern lives possible
· Iron is the fourth most abundant mineral in the earth's crust. Soils and rocks in Minnesota may contain minerals very high in iron, so high in fact, that taconite can be mined for its iron content. Iron gives the hemoglobin of blood it's red color and allows the blood to carry oxygen. The iron in a metal pail turns to rust when exposed to water and oxygen.

Several taconite mines and processing facilities are currently operating on the Mesabi Range. It has long been the goal of Mesabi miners to produce a pure iron product in northern Minnesota. In 2010 a new plant began production of 97% iron nuggets. The nuggets, along with iron and steel scrap, are used in electric arc steelmaking furnaces.

Minnesota's iron ore was actually discovered while prospectors were searching for gold. Since the object of their search was gold, the iron was ignored. It turned out the iron would become much more valuable to northern Minnesota than the small amount of gold found. Iron ore was discovered on the three iron ranges at different times. The first ore shipped from the Vermilion Range was in 1884 ...
