1.Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. ... To put it in a simple way decantation is separating an immiscible solution by transferring the top layer of the solution to another container.
2.Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. Either the clarified fluid or the solid particles removed from the fluid may be the desired product.
3.Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is evaporating into a gas, called water vapor.
4. Sieving is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one another and the screen openings. ... Sieves are also used to separate stones from sand.
5.The use of a bar magnet is one of the simplest and easiest ways of physical separation of magnetic substances from non-magnetic substances. This is done by passing the magnet over the mixture when it will pick the magnetic substance out of the mixture.
