  • Iron mining in the United States - Wikipedia

    Iron mining in the United States produced 42.5 million metric tons of iron ore in 2015, worth US$3.8 billion. Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah.Most of the iron ore was mined in northern Minnesota's Mesabi Range.

  • Iron Ore Statistics and Information - USGS

    Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3).. Iron ore is the source of primary iron for the world's iron and steel industries.

  • Iron and steel industry in the United States - Wikipedia

    In 2014, the United States was the world’s third-largest producer of raw steel (after China and Japan), and the sixth-largest producer of pig iron.The industry produced 29 million metric tons of pig iron and 88 million tons of steel. Most iron and steel in the United States is now made from iron and steel scrap, rather than iron ore.
