IRON ORES The term iron ore is limited to oxides of iron, either as such or in combination with water or carbonic acid Other compounds of iron, as for example the sulphide, are not adapted for iron making The term is further limited to deposits of sufficient purity and richness to render smelting profitableIron Ore Iron ores are divided into two different groups according to their magnetic susceptibility, that is, strongly magnetic iron ore such as magnetite and weakly magnetic iron ores (oxidized iron ores) including martite, hematite, specularite, limonite, and sideriteIron Ore an overview ScienceDirect TopicsIron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching 1,500 °C (2,730 °F) or higher, about 500 °C (900 °F) higher than that required to smelt copperIron WikipediaOther ores include siderite (ferrous carbonate, FeCO 3), taconite (an iron silicate), and magnetite (ferrousferric oxide, Fe 3 O 4), which often occurs as a white sand Iron pyrite (iron disulfide, FeS 2) is a crystalline goldcolored mineral known as fool's gold Chromite is a chromium ore that contains ironiron: Natural Occurrence Infoplease©Encyclopedia of Life Support Systems (EOLSS) 1 Introduction Iron and manganese ores are hosted by deposits of various size, grade, and origin However, more than 95% of all deposits exploited today are of sedimentary origin and originated as Iron and Manganese Ore Deposits: Mineralogy, Geochemistry
