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.Learn More
