Magnetite

Magnetite

Magnetite (Fe3O4) is a naturally occurring iron oxide mineral known for its strong magnetic properties. It is also a major iron ore, meaning it’s a source of iron used in steel production. Magnetite is ferrimagnetic, meaning it’s strongly attracted to magnets and can be magnetized itself.

Key characteristics of magnetite:

  •  

  • Chemical formula: Fe3O4
  • Magnetic properties: Strong ferrimagnetism, meaning it’s strongly attracted to magnets and can be magnetized
  • Color: Typically black or grayish-black
  • Appearance: Can be found in crystals or as massive rock
  • Iron ore: An important source of iron for steel production
  • Occurrence: Found in igneous, metamorphic, and sedimentary rocks, as well as in ore deposits

Other names for magnetite:

  • Lodestone: Another name for magnetite, particularly referring to its magnetic properties
     
  • Black ore: A term for magnetite, referring to its color

Uses of magnetite:

  • Steel production: A major iron ore for steel manufacturing.
  • Industrial applications: Used in various industries where its magnetic properties are beneficial, such as foundry, energy storage, and iron catalysts
