Description

Iron ore is a naturally occurring mineral substance composed primarily of iron oxides such as hematite (Fe₂O₃), magnetite (Fe₃O₄), goethite (FeO(OH)), and limonite (FeO(OH)·nH₂O). It serves as the main raw material for the production of iron and steel, which are essential to global industrial development.

Typically found in sedimentary rocks, iron ore is extracted through open-pit or underground mining and then processed through crushing, screening, and beneficiation to increase the iron content and remove impurities. High-grade iron ore usually contains between 58% and 67% iron (Fe).

The color of iron ore ranges from dark grey and rusty red to deep brown, depending on the type and oxidation level. Major iron ore producing regions include Australia, Brazil, China, India, and Africa.

Common Types of Iron Ore:

1. Hematite (Fe₂O₃): High-grade ore with excellent iron content and minimal impurities.

2. Magnetite (Fe₃O₄): Contains high iron content and magnetic properties, often processed into pellets for steelmaking.

3. Limonite (FeO(OH)·nH₂O): Lower-grade ore, typically found in weathered deposits.

4. Goethite (FeO(OH)): A hydrated iron oxide often associated with limonite deposits.

Uses:

Primary raw material in steel manufacturing.

Used in construction, automotive, shipbuilding, and heavy machinery industries.

Occasionally used in pigments, water treatment, and chemical catalysts.
