The Mesabi Iron Range is a vast deposit of iron ore and the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota. It is the chief deposit of iron ore in the United States. The deposit is located largely in Itasca and St. Louis counties. It was extensively worked in the earlier part of the 20th century. Extraction operations declined throughout the mid-1970s but rebounded in 2005. China's growing demand for iron made taconite production profitable again and some mines that had closed were reopened. This heap of iron ore pellets will be used in steel production. ...

Most of the world's iron ore, including that which forms the Mesabi Iron Range, was formed during the middle precambrian period about 2 billion years ago. During this period, major erosion occured which levelled mountains that were formed during the previous 2 billion years. This ersosion released iron and silica which settled into the waters of a new sea. It is theorized marine algae living in this new sea raised the level of atmospheric oxygen, which combined with the iron released during erosion causing the iron to precipitate into the iron formations of the Mesabi range.

Iron ore is mined from both underground mines and open pits. Much of the softer ore was formed close to the surface, allowing mining operations to be conducted via the open pit mines. The world's biggest open pit iron ore mine is the Hull-Rust-Mahoning Open Pit Iron Mine in Hibbing Minnesota. The El Chino mine located near Silver City, New Mexico is an open-pit copper mine Open-pit mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. ...

Open pit mines that are not worked anymore are a common feature along the iron range and have been the site of further development. The Virginia Pilot for example focuses on grounds adjacent to the mines for redevelopment into low to moderate income residential space. The high water table in this region means that once pumping stops, the abandoned mines themselves are quickly filled in with water. Ore was primarily shipped by railroad to the port cities along Lake Superior, such as Two Harbors and Duluth, Minnesota.
