  Hematite - an overview | ScienceDirect Topics

  Hematite is a kind of accessory mineral widely distributed in various rocks and appears in many igneous rocks in fine granular form. Under special circumstances, hematite forms huge blocks in regional metamorphic rocks. Besides, hematite is often produced together with magnetite and can be employed for iron making, red pigment and abrasive.
