Notes On Concentration of Ores - CBSE Class 12 Chemistry

Magnetic separation is used when either the ore (or) the impurities in it are magnetic in nature. Ex: Separating iron from its ore hematite Froth flotation separates the gangue particles from the ore, based on the fact that gangue is wetted by water, while mineral is wetted by oil. The ore is crushed into fine powder and mixed in water.
