Hematite for which Magnetite is occasionally mistaken has a dark red streak and is not attracted by a magnet. Heating magnetite to 550 degrees C however alters the mineral to hematite and causes loss of its magnetic property. Magnetite alters to limonite and to hematite.

In Asia, a great deal of mining for hematite ore is done in China. Known reserves include the Tung-Yeh-Chen hematite deposit and the Dongye hematite deposit. One of the major advantages hematite ore has over other types like magnetite is its high iron content. That makes the iron extraction process much less costly and time consuming.
