Graph of usable iron ore mined in the United States 1890–2014, data from USGS. In common with other commodities, the history of iron mining in the United States includes a shift to larger but lower-grade ore deposits, a shift from underground to open-pit mining, and a shift from labor-intensive mining to highly mechanized mining.
The repository is constantly seeking donations of mine maps to add to the microfilm/digital collection. [12] When maps are received from a donor, they are scanned and stored in both microfilm and digital archives. The maps, along with a scanned images (upon request), are returned to the donor. The repository does not retain hard copies of maps.
Steel production by countries. United States steel production faced a steep decline in the 1970s. As the only major steel maker not harmed during World War II, the United States iron and steel industry reached its maximum world importance during and just after World War II. In 1945, the US produced 67% of the world's pig iron, and 72% of the steel.
Despite several small mining endeavors beginning in the 17th and 18th centuries, mining did not gain major traction in the United States until the 19th century. [23] In terms of technology, explosives such as black powder were phased out as dynamite increased in popularity as a new mining method in the 19th century. [ 23 ]

Iron ore is currently mined only from open pits, although some mines operated underground early on. [10] Much of the softer ore was formed close to the surface, allowing mining operations to be conducted via open pit mines. The world's largest open pit iron ore mine is the Hull–Rust–Mahoning Open Pit Iron Mine in Hibbing. In the early years ...
