Mining of Iron Ores IspatGuru

The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.

Iron Ore Mining Techniques Metal Extraction

Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

Iron mining in the United States Wikipedia

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 past 50 years, more than 90 percent of US iron ore production has been mined from the Lake Superior deposits. None of the iron ore now mined in the US is “direct shipping” ore ready to be fed into the iron- and steel-making process. The ore is concentrated to raise the iron

How Is Iron Extracted From the Earth? Reference

26-03-2020  Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
