Iron ore - Wikipedia
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO,Iron Ore Company of Canada - Rio Tinto,The Iron Ore Company of Canada (IOC) operations are integrated across a mine and processing plant in Labrador City, Newfoundland and Labrador; a port and stockpile in Sept-Iles, Quebec; and a 418 kilometre railway that joins these two parts of the operation.Ore - Wikipedia,Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit.
