Iron Mines in Michigan - NASA

The Operational Land Imager (OLI) on Landsat 8 captured this image of iron mines in northern Michigan on September 11, 2013. Although the mined areas look like one facility from a satellite perspective, there are two separate mines in this scene. The Empire Mine, which produces about 5.5 million tons of magnetite each year, is on the east side ...


The Jackson County Iron Company operated a surface taconite mine from 1968 to 1982. The site was about 1,300 acres, including the open-pit mine, associated processing facilities and disposal areas for encompassed mine tailings and waste rock. Following the passage of state mining laws, the DNR issued a mining permit in 1981.

ANCIENT MINING - Earth Sci

Likely mine sites were identified by surface finds. Ore was extracted and removed by iron hand tools, and lifted up the shaft using a rope. In the 16th century, miners were still using fire-setting and wooden trays. In 1600 years, mining technology progressed very little beyond the Roman practices.

This is because lower iron content in the ore will render all the money and effort exerted in mining the ore from under the surface of the earth a big waste. This is why minerals near the surface of the earth and containing as a high percentage of iron are mined for the production of iron.


US iron mining is most prevalent in Minnesota and Michigan. The majority of the mining found for these operations is Surface Mining. This form of mining is when minerals are directly removed from the ground surface area. It is also commonly known as "open cast mining", making up the majority of metal ore mining.

Kiruna (Fig. 4) is the largest, most famous and at the same time northernmost mine. The ore body in Kiruna is a massive block of high-grade magnetite ore, 4 km long, 80 m wide and extending over a depth of 2 km. Fig. 5 shows the proven existing reserves of iron ore at the 4 LKAB mines, as well as the iron grades of the ores in the reserves.


deposits are very deep, and in open-pit mines when the deposits are relatively shallow.i Once the metals have been separated from other rock, the mining operator must find ways to dispose of the substantial waste rock. Sulfide mining is different from traditional iron ore mines and taconite mining (sometimes referred to as ferrous mining).
