- 1SievingMethod of separation of particles from a mixture based on the difference in size of particles is known as sieving. It uses sieve plates for separation of coarse particles from finer particles.
- 2EvaporationTechnique used to separate out homogeneous mixtures where there is one or more dissolved salts. The method drives off the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains.
- 3DistillationPurification process where the components of a liquid mixture are vaporized and then condensed and isolated.
- 4DecantationProcess for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture, the less dense liquid is poured leaving the other component behind.
- 5CrystallizationProcess through which the atoms/molecules of a substance arrange themselves in a well-defined three-dimensional lattice and, consequently, minimize the overall energy of the system.
- 6FiltrationUsed to separate out pure substances in mixtures comprised of particles, some of which are large enough in size to be captured with a porous material.
- 7MagnetismProcess of separating components of mixtures by using magnets to attract magnetic materials.
- 8Paper ChromatographyAnalytical method used to separate colored chemicals or substances, involves using two solvents and rotating the paper 90° in between. This is useful for separating complex mixtures of compounds having similar polarity, for example, amino acids.
- 9CentrifugingUsed for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. It's based on rotary force.
