Iron Ores (Hematite and Magnetite) - GeeksforGeeks

Hematite 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.

Is Hematite Magnetic - Orgone Energy

Hematite is not magnetic and shouldn't respond to a common magnet. However, there are many hematite specimens containing enough magnetite which makes them attracted to a common magnet. This usually leads to a wrong assumption that the piece is magnetite or pyrrhotite, which is weakly magnetic. So, it is important to check other properties to ...
