Iron filings can be separated from a heterogenous mixture using the technique of :
-
- Sublimation
- Magnetization
- Sedimentation
- Evaporation
- Sublimation

The method of separation using magnets is used when one of the components is magnetic. So the heterogeneous mixture of iron filings and some other material (such as sulphur powder) can be separated by using magnets. Similarly, a mixture of sand and iron filings can be separated by magnet.
