Although in 2014, the US mined only 1.8 percent of all iron ore mined worldwide, the US was previously a much larger factor in the world iron ore market. From 1937 through 1953, US iron ore made up more than a third of the world's iron ore production; the proportion of world iron ore mined in the US peaked in 1945 at 56 percent.
The company had made steel in Scranton, Pennsylvania since 1840, but moved to provide easier access to iron ore, and in an unsuccessful attempt to avoid labor troubles. Birmingham, Alabama became a major steel producer in the late 1800s, using locally mined coal and iron ore. The iron ore was mined from the Red Mountain Formation of Silurian age.

For each commodity they quote a range (low and high price) which reflect the buying and selling about 9-fold due to China's transition from light to heavy industry and its focus on manufacturing. [2] (China became the world's largest consumer of iron ore in 2003, [3] and accounts for over half of global metal consumption.) [4]
Iron ore, coke, and flux are fed into the blast furnace and heated. The coke reduces the iron oxide in the ore to metallic iron, and the molten mass separates into slag and iron. Some of the iron from the blast furnace is cooled, and marketed as pig iron; the rest flows into basic oxygen furnaces, where it is converted into steel.
The main constraint is the position of the iron ore relative to market, the cost of rail infrastructure to get it to market, and the energy cost required to do so. Mining iron ore is a high-volume, low-margin business, as the value of iron is significantly lower than base metals. [24]
