Lake Superior Iron Ranges]]
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. Discovered in 1866, it is the chief deposit of iron ore in the United States. The deposit is located in northeast Minnesota, largely in Itasca and Saint 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, along with the falling value of the US dollar versus other world currencies, have made taconite production profitable again, and some mines that had closed have been reopened, while current mines have been expanded.
The Mesabi Range was known to the local Ojibwe as Misaabe-wajiw, meaning "Giant mountain". Throughout the Mesabi Range, "Mesaba" and "Missabe" spelling variations are found along with places containing "Giant" in their names.
There are three iron ranges in northern Minnesota, the Cuyuna, the Vermilion, and the Mesabi. Most of the world's iron ore, including that contained in northern Minnesota, was formed during the middle Precambrian period. During this period, erosion leveled mountains. This erosion released iron and silica into the waters of a new sea. Marine algae living in this new sea raised the level of atmospheric oxygen. This oxygen catastrophe caused the eroded iron to precipitate into the banded iron formations found in northern Minnesota and other members of the Animikie Group. Over billions of years, geological forces left behind ore deposits of varied quality and concentrations - differences that would determine how the ore was mined from place to place. On the Vermilion Range, between Soudan and Ely, lay the deepest veins of ore. There, miners worked in deep underground mines, blasting the ore from volcanic bedrock. On the Mesabi Range, stretching 100 miles from Grand Rapids to Babbitt, soft ore lay close to the surface, where it could be scooped from open pit mines. 
The Mesabi Range is 110 miles (177 km) long. Heights vary from 200 to 500 feet (61 to 152 meters). The highest point is approximately 2,000 feet (610 meters). The range trends from the northeast to the southwest, extending from Babbitt to Grand Rapids.
Iron ore is currently mined only from open pits, although some mines operated underground early on. The Soudan Underground Mine is the oldest mine in Minnesota. In the late 19th century prospectors searching for gold in northern Minnesota discovered extremely rich veins of hematite at this site, often containing more than 65% iron. An open pit mine began operation in 1882, and moved to underground mining by 1900. The mine was worked until the end of active mining in 1962, and was then donated to the State of Minnesota to use for educational purposes.
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 of mining from the late 19th century until the 1950s, mining focus was on high grade ore that could be processed into steel without much change. However, when that supply dried up, focus shifted to lower-grade ore (taconite) which requires extensive processing at large mining-processing facilities before moving to port. The mined ore is then transported, primarily by the Duluth, Missabe and Iron Range Railway, to the ports of Two Harbors and Duluth. At Duluth, trains of up to eighty 100-ton open cars are moved out on massive ore docks to be dumped into "lakers" of up to 60,000 tons weight for movement to steel mills in Indiana and Ohio.
Open pit mines that are no longer worked are a common feature along the Iron Range. Some of these sites have been redeveloped for other uses. For instance, the Virginia Pilot is a project which focuses on redeveloping the grounds adjacent to the old mines into low- to moderate-income residential space. The Hill-Annex Mine is now a state park and offers tours to visitors who wish to learn about mine operations. Tours are guided by former mine workers.
Currently, there are six mining-processing facilities in operation on the Iron Range. Cliffs Natural Resources owns and operates Northshore Mining, which has mining operations in Babbitt and crushing, concentrating (grinding) and pelletizing operations in Silver Bay, along with United Taconite which has mining operations in Eveleth and crushing, concentrating and pelletizing operations in Forbes. Arcelor Mittal owns and operates the Minorca Mine and Plant with mining operations near Biwabik and Gilbert and a crushing, concentrating and pelletizing facility near Virginia ( ). United States Steel owns and operates both KeeTac ( ) and Minntac ( ) with mining and processing facilities in Keewatin and Mountain Iron respectively. The last facility is Hibbing Taconite which operates a mine and plant between the cities of Hibbing and Chisholm. Although Arcelor Mittal owns a majority stake in Hibbing Taconite, the operating agent is actually a minority owner, Cliffs Natural Resources. United States Steel is also a minority stakeholder in Hibbing Taconite.
In addition, Essar Steel is building a mine/plant near Nashwauk that has plans to not only mine and process the taconite, but eventually to produce steel on-site ready for shipment around the world. Steel Dynamics and Kobe Steel own Mesabi Nugget ( ) near Hoyt Lakes which does not yet mine its own material, but does produce high-iron content nuggets. Magnetation, Inc. is another company currently working the Iron Range, but their focus is reclaiming leftover iron from ore dumps with company-designed high-power magnetic separators to produce concentrate to sell and ship throughout the world.
Several large-scale strikes took place on the Mesabi Iron Range during the early 1900s. The first began on July 20, 1907 after the Western Federation of Miners (WFM) asked Oliver Iron Mining Company for, among other demands, an eight-hour work day and a pay raise. The strike lasted two months and resulted in thousands of workers being blacklisted.
In June 1913, the WFM organized a strike of the copper companies in the region, again demanding shorter hours and better pay. This unsuccessful strike lasted 265 days and is known as the Copper Country Strike of 1913–1914.
On June 25, 1916, a miner left his shift after being paid less than the contracted rate. His action led to the Mesabi range strike of 1916. The Industrial Workers of the World quickly supported the strike for better pay and shorter hours. In September 1916, the workers voted to resume work, assuming a failed strike. However, shortly after returning to work a 10% raise in wages was issued for workers throughout the Range.

Bob Dylan memorialized the Iron Range in the 1963 song North Country Blues, a lament portraying hard times in the region. Presented in his 1964 album The Times They Are a-Changin', it includes such lines as:
- So the mining gates locked and the red iron rotted
- And the room smelled heavy from drinking
- When the sad, silent song made the hour twice as long
- As I waited for the sun to go sinking 
The Mesabi Range was brought to public attention by the 2005 film North Country, which depicts a fictionalized version of the events surrounding Jenson v. Eveleth Taconite Co., a sexual harassment, class-action lawsuit that female miners brought against a Mesabi Range mining company.
- From the Monongahela valley, to the Mesabi Iron Range –
- To the coal mines of Appalachia, the story's always the same.
Springsteen lifted the two lines of the above lyric from the opening voice-over by Gregory Peck in the 1945 movie The Valley of Decision set in a Pennsylvania steel town.
"Mesabi" is the title song of a 2011 album by Tom Russell: "Some things never change on the Mesabi Iron Range . . . Bethlehem of the Troubadour Kid" (referring to Bob Dylan — see above).
