In the Lake Superior Basin, low-grade iron mining is conducted exclusively by open-pit mining methods. The scale of the land alteration associated with modern iron mining is enormous, and is unlike the historic mining of the 19th and early 20th centuries. For example, U.S. Steel's Minntac mine project covers an area of approximately 20,000 acres.
