- 1SievingUsed method for separating particles of different sizes. (like stones from sand)
A sieve such as used for sifting flour has very small holes. - 2EvaporationUsed method to separate out homogeneous mixtures where there is one or more dissolved salts.
The method drives off the liquid components from the solid components. - 3DistillationUsed method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture.
To separate liquids. - 4DecantationUsed method to separate immiscible liquids that have different densities.
- 5CrystallizationUsed method to separate components from a liquid mixture which may be an impure melt or a solution, one or more components are dissolved in it.
- 6FiltrationUsed method of separating suspended solid matter from a liquid, by using a filter to pass through the pores of some substance.
- 7MagnetismUsed method of separating components of mixtures by using magnets to attract magnetic materials.
- 8Paper ChromatographyUsed method for separating dissolved chemical substances by taking their different rates of migration across sheets of paper.
- 9CentrifugingUsed method for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed.
