Separation by melting and by magnets

LC1.1.3.3

To carry out all experiments from this subject area, we offer you a complete set: CLICK HERE

Description

The students learn about two other separation methods called separation by melting and by magnets. They separate sulphur powder from sea sand using the melting-out method and iron powder from polystyrene using the magnetic separation method. You will realise that the material properties of melting point and magnetisability make these separation processes possible.
