  Types of Iron Ore: Hematite vs. Magnetite - MineListings.com

  201614 · Types of iron ore: Hematite Hematite ore has the chemical formula Fe2O3 and has very high iron content of 70 percent. Its name comes from the Greek word for blood, haima, because of its reddish color. High-grade hematite ore is also often referred to as direct-shipping ore because it is mined and extracted with a fairly simple crushing and …

  Growth behavior of the magnetite phase in the reduction of hematite …

  2019104 · To understand the formation and growth mechanism of the magnetite phase during the fluidized reduction of hematite, a high-purity hematite ore was isothermally reduced using a 20vol% CO?80vol% CO2 gas mixture in a micro-fluidized bed to examine the process of the selective conversion of hematite to magnetite. The micro-structural …
