Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore …

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 …
