Question

Give the principle and examples of the following.

Magnetic separation

Answer 1

Magnetic separation is based on the difference in magnetic properties of the components of an ore. The magnetic particles are attracted by a magnet, while the non-magnetic particles are not.

Examples:

• Magnetite (Fe₃O₄) is separated from impurities by magnetic separation.
• Chromite (FeCr₂O₄) can also be concentrated by magnetic separation.
