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 Green Tree facility provides and stores, digitally and in microfilm (aperture cards), [4] over 182,000 maps of abandoned mines. This repository contains maps of mine workings from the 1790s to the present day. [5] It serves as a point of reference for mine maps and other information for both surface and underground mines throughout the ...
Gilbert (pop. 1,799) is the location of Lake Ore-be-gone, an artificial lake created by flooding three open-pit iron ore mines. Hibbing (pop. 16,361) is the largest city by area in the state of Minnesota. It is home to the Hull–Rust–Mahoning Open Pit Iron Mine, one of the world's largest open pit iron mines.

These mines were mainly of the underground shaft type, which were among the deepest iron mines in the country. Due to these characteristics, and the greater associated costs involved with extracting the ore, these mines were unable to compete economically with the larger open pit iron mines in northern Minnesota and elsewhere.
The mine, located in the Mesabi Range, supplied as much as one-fourth of all the iron ore mined in the United States during its peak production from World War I through World War II. This prodigious output made Minnesota the nation's largest iron ore producer and the U.S. the world's largest steel manufacturer. [3]
