Iron ores are dressed by:
Froth floatation process
Hand-picking
Magnetic separation
None of these
Answers (1)
As we have learnt,
Magnetic Separation Method
This is based on differences in magnetic properties of the ore components. If either the ore or the gangue is attracted towards the magnetic field, then the separation is carried out by this method.
For example, iron ores are attracted towards the magnet, hence, non–magnetic impurities can be separated from them using magnetic separation.
If ore and not the gangue or the gangue and not the ore is attracted by a magnet, the two can be separated by this method.
Therefore, Option(3) is correct.
