Question
Which of the following ores has magnetic properties?
- Galena
- Zinc blende
- Hematite
- Zincite
Hint:
Hematite has magnetic property.
The correct answer is: Hematite
True hematite, though iron containing, actually has a weak magnetic field because of the way its iron atoms are aligned. On the other hand, the mineral magnetite is highly magnetic, and many often erroneously assume it is magnetic hematite.
