    Magnetizing roasting uses temperatures between 700 and 900 °C for a time of under 1 hour to produce an iron concentrate (Fe 3 O 4) to be used for iron smelting. For magnetizing roasting it is important to have a reducing atmosphere to prevent oxidization and the formation of Fe 2 O 3 because it is harder to separate as it is less magnetic.

  • Why we use hematite over magnetite as iron ore?

    Magnetite has more iron content. Hematite ore is simply mined, crushed, and after that screened into either lump or fines. It is then immediately sold as such. The ore has high iron content, typically between 56% and 64% Fe. Magnetite has higher iron content than hematite.
