Iron is a common metal found in the earth's crust, where it occurs in combination with other elements. The term "iron ore" is used when the rock is sufficiently rich in iron minerals to be mined economically. Iron ore yields metallic iron (Fe) when heated in the presence of a reducing agent such as coke. Iron ore usually consists of …

Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.

21. When miners in the ancient world went looking for materials in the earth, like gold or iron, did they have ways of predicting where those might be found? For example, we now know that diamonds are often found in cone-shaped deposits in old volcanos, but that knowledge is related to the study of geology and our understanding of how diamonds ...

Much of the initial iron mining west of the Blue Ridge involve limnite deposits. The first limonite mining was around 1760; the ore was processed in a bloomery near the Shenandoah River. Like all colonial-era iron production, the bloomery was fueled by charcoal. There are limonite deposits in Pulaski and Smyth counties.
