Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Hematite is an iron oxide mineral. It is non-magnetic ...

Abstract. Oolitic iron ores are made up of silicate, oxide, and carbonate minerals that are part of solid solution series. The compositions of the minerals can depart from pure end members and show variation among deposits. This variability can be quantified using electron microprobe techniques. Iron silicates are represented by chamositic ...

Oolitic iron ores can be classified as sedimentary oolitic ironstones and include deposits in Germany (Minette), Australia (Pilbara and Roper River), Canada (Peace River), Colombia (Paz de Rio) and the United States (Clinton). Oolitic iron ores often contain high levels of phosphorus that resist conventional mineral processing methods.
