Key Differences
- ◆ Magnetite is strongly magnetic; hematite is not (except in some varieties).
- ◆ Hematite has a distinctive reddish-brown streak; magnetite has a black streak.
- ◆ Hematite is Fe2O3 (ferric oxide); magnetite is Fe3O4 (mixed ferrous/ferric oxide).
- ◆ Hematite color ranges from steel-gray to reddish-brown; magnetite is always black.
- ◆ Both are iron ores, but hematite is the primary commercial ore due to its higher iron content.
