According to Ducksters, variable methods of separating mixtures exist, such as filtration, distillation and centrifuge. Other methods include chromatography, sublimation and crystallization. Separating mixtures is useful for isolating or extracting a particular substance from another.
Filtration is a common method which utilizes a barrier or filter in order to separate solid, small particles from a gaseous or liquid suspension. A very fine mesh is often used to filter the smaller particles. Distillation involves boiling a liquid suspension in order to cause the liquid to evaporate and leave behind solid residue. However, different substances have different boiling points, so filtration is not useful for all materials.
