Iron Ores (Hematite and Magnetite) - GeeksforGeeks
Hematite is an iron ore that contains iron in the form of Fe 2 O 3. It is a significant source of iron extraction. Hematite is a mineral that is paramagnetic. As a result, it can be drawn to an external magnetic field. Hematite is abundant in rocks and soil. Hematite's magnetic properties are caused by unpaired electrons.
