Elemental iron is virtually absent on the Earth's surface except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.Although iron is the fourth most abundant element in Earth's crust, composing about 5% by weight, [4] the vast majority is bound in silicate or, more rarely, carbonate minerals, and smelting pure iron from these minerals would require a prohibitive ...
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.

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;
An iron plantation in the Hopewell Furnace National Historic Site a living history museum in Elverson, Pennsylvania. Iron plantations were rural localities emergent in the late-18th century and predominant in the early-19th century that specialized in the production of pig iron and bar iron from crude iron ore. [1]
Since ore shipments began in 1895, over 1.4 billion tons of waste material and 800 million tons of iron ore have been removed from the 2,000-acre (800 ha) mine site. [2] The mine was listed as a National Historic Landmark and added to the National Register of Historic Places on November 13, 1966. It was listed for its national significance in ...
The East Texas iron ore belt refers to a significant region in East Texas characterized by the presence of iron ore deposits, primarily associated with the Weches greensand formation. This area has historical importance in the mining industry, contributing to the supply of iron ore in the United States. Although many counties in this region ...
Iron metallurgy in Africa concerns the origin and development of ferrous metallurgy on the African continent.Whereas the development of iron metallurgy in North Africa and the Horn closely mirrors that of the Ancient Near East and Mediterranean region, the three-age system is ill-suited to Sub-Saharan Africa, where copper metallurgy generally does not precede iron working.
