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 or-intensive mining to highly mechanized mining. Although in 2014, the US mined only 1.8 percent of all iron ore mined worldwide, the US was previously a much larger factor in the world iron ore market. From 1937 through 1953, US iron ore made up more th
