An easily accessible source of iron ore is so-called "bog iron", formed naturally in bogs or swamps by the oxidation of iron minerals dissolved in water. It can be identified by its reddish brown color and uneven texture. Early metallurgists identified bog-iron deposits by indicators such as withered grass, a wet environment, hygrophilous grass-dominated vegetation, and reddish-brown solutions or depositions in nearby waters. Chemically, bog iron is mostly made up of the mineral geothite, a form of iron oxyhydroxide that is also the main component of rust. Because iron-bearing water continues to flow into a bog over time, the iron in a given bog will replenish over the course of a few decades. | An easily accessible source of iron ore is so-called "bog iron", formed naturally in bogs or swamps by the oxidation of iron minerals dissolved in water.

Iron ores are rocks and minerals from which metallic iron can be extracted.
Uses
The primary use for iron ore is the production of iron, including sponge iron and pig iron. Some forms of iron ore also have other uses, such as in the pigment ochre.
Natural Sources
Bog Iron
An easily accessible source of iron ore is so-called "bog iron", formed naturally in bogs or swamps by the oxidation of iron minerals dissolved in water. It can be identified by its reddish brown color and uneven texture. Early metallurgists identified bog-iron deposits by indicators such as withered grass, a wet environment, hygrophilous grass-dominated vegetation, and reddish-brown solutions or depositions in nearby waters. Chemically, bog iron is mostly made up of the mineral geothite, a form of iron oxyhydroxide that is also the main component of rust. Because iron-bearing water continues to flow into a bog over time, the iron in a given bog will replenish over the course of a few decades.
