Iron ore Croft Mine Historic Park Soudan Underground Mine State Park. From a geological perspective, Minnesota's Iron Range includes these four major iron deposits: [4] Mesabi Range, the largest iron range, largely within Itasca and Saint Louis counties; Vermilion Range, northeast of the Mesabi, in Saint Louis and Lake counties;
Iron ore was the third-highest-value metal mined in the United States, after gold and copper. [2] Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah. Most of the iron ore was mined in northern Minnesota's Mesabi Range. Net exports (exports minus imports) were 3.9 million tons.
