Magnetite Black Oxide

General Application

Magnetite is used as a raw black pigment in ceramic glazes, as well as non-ceramic products like polishing compounds, cosmetics, medicines, fillers, construction materials, and inks. As the most magnetic mineral on Earth, magnetite is highly effective as a contrast agent in Magnetic Resonance Imaging (MRI). Also known as black iron oxide, magnetite is a reliable source of iron for ceramic applications

  • Cost effective
  • Provides ceramic glaze colouration after being fired at high temperatures
  • Suitable for corrosion-resistant purposes and paints
  • Suitable for coal washing due to high density and fine milling
  • Able to be recovered by magnetic separation after coal washing
  • Non-fouling; subsequent treatment stages are unaffected by trace deposits
  • High purity; free of hematite, sulphides, etc.



Ferrous iron oxide magnetite (Fe304) is the concentrate of magnetite ore that contains 96% magnetics. Higher iron levels can be achieved through further magnetic separation and milling.

  • Durable and stable
  • Grain size ranges from coarse to ultra-fine
  • Meets requirements of centrifuge-assisted dense medium separation and coal preparation


General Information

Magnetite is named for its strong magnetism. It is a lustrous, black mineral that occurs naturally in igneous and metamorphic crystals, masses, and as a loose sand. The magnetism is generated by the spinel arrangement with transference of electrons between the two different ions.
