Out of the listed ores, how many can be enriched using the magnetic separation technique?

1. 1
2. 2
3. 3
4. 4

Correct answer: 2

Solution

Magnetic separation is used when either the ore or the gangue is magnetic and the other is not. From the given set, only two ores satisfy this condition, so the answer is 2.
