Question

Magnetic separation method is only used when either of the two, the ore or the gangue, is magnetic.

• A. True
• B. False

Answer 1

The correct option is A True

• An ore may be defined as a mineral from which metal can be extracted economically in a simpler way on a large scale.
• The extracted ore contains a large number of unwanted earthly materials like sand, soil, waste rocks, etc. which is known as the gangue. Gangue can be acidic or basic.
• Magnetic separation method is based on the difference in the magnetic properties between ore and the gangue. This method is only used if either the ore or the gangue is magnetic.

Hence, the given statement “Magnetic separation method is only used when either of the two, the ore or the gangue, is magnetic” is true.
