Mix

Sieving – use to separate different sized solid particles of various sizes. Used in banks, mining industry and to sort foodstuffs.
Filtration – used separate an insoluble substance from a liquid. Un-dissolved solid particles are separated from a liquid (or gas) by passing the mixture through a screen such as filter paper that is fine enough to collect particles of solid.
Evaporation – evaporation separates soluble substance from a solution.
Distillation – used to purify liquids (to obtain a solvent from a solution). It involves boiling a liquid and cooling the gas produced to condense it back to the liquid state. Effective when the components have different boiling points.
Solution – is used as a separation process because of the fact that some constituents of a mixture dissolve in a solvent such as water more readily than others. Solution is usually used in combination with filtration, evaporation or crystallization.
Decantation – is the process of pouring off a liquid from above a solid that has been allowed to settle by sedimentation.
Sedimentation – occurs when solid particles are allowed to settle from water (or other liquids) or air. This occurs most readily if the water or air is not moving.
Centrifugation –separates mixtures of chemicals using a spinning motion in a machine called a centrifuge. It is commonly used to separate liquids from solids in a manner similar to, but faster than sedimentation.
Fractional distillation – is the separation of a mixture of several different liquids with similar boiling points. The process involves numerous, vaporization – condensation steps through which the components are gradually separated.
