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 Fe (Element) PubChem

Iron is hard, brittle, fairly fusible, and is used to produce other alloys, including steel. Wrought iron contains only a few tenths of a percent of carbon, is tough, malleable, less fusible, and usually has a "fibrous" structure. Carbon steel is an alloy of iron with small amounts of Mn, S, P, and Si.

Reduction of Iron Oxides with Hydrogen—A Review

In general, the reduction of Fe 2 O 3, called hematite, does not occur directly to metallic iron, Fe.If the reduction temperature is lower than 570 °C, reduction to Fe occurs stepwise from Fe 2 O 3 to Fe 3 O 4, called magnetite, and continues to Fe.The intermediate oxide, wüstite Fe (1−x) O, is not stable at temperatures lower than 570 °C. At reduction temperatures higher than 570 °C

Analysis: Iron ore 65% Fe fines premiums rise as China

The Platts 62%-65% Fe spread widened in the past month and was at $17.60/dmt on Tuesday, up from April's average of $15.47/dmt. Higher iron ore prices and wider spreads with 65% Fe index are adding to costs for steelmakers, with many in Europe operating close to breakeven cash margins, despite lower benchmark premium coking coal prices in April.
