Separating Mixtures

Many methods of separation are used in the home and industry to remove unwanted materials from the required product or to test the properties of different materials. Some of the methods of separation you may have learnt about in class include the following:
  1. Distillation
  2. Filtering or Seiving
  3. Centrifuging
  4. Magnetic separation
  5. Crystallization
  6. Evaporation
  7. Chromotography

Investigate the separation of mixtures in industry or devise a method of separation to solve a problem (for example, separating metals at a land fill site, separating different materials in electronic waste or recycling waste water).
