SEPARATION TECHNIQUE
BY: GROUP 1
SEPARATING COMPONENTS OF A MIXTURES
It is possible to separate the components of a mixtures. Since the components are not chemically, they can be separated by physical means. The difference substances in a mixture can be separated from one another by taking advantage of their unique properties.

What is Decantation?
DECANTATION is to draw off a liquid
without disturbing the sediment or the lower liquid layers.
DECANTATION
What is Mechanical Separation
MECHANICAL SEPARATIONA group of laboratory and production
operations whereby the components of a poly phase mixture are separated by mechanical methods into two or more fractions of different mechanical characteristics. The separated fractions may be homogeneous or heterogeneous, particulate or non particulate.
MECHANICAL SEPARATION
What is Filtration?
FILTRATIONThe process of
separating solid from a liquid by allowing the liquid to pass through a porous material such as a filter paper.
FILTRATION
WHAT IS EVAPORATION?
EVAPORATIONEvaporation is a type of
vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.
EVAPORATION
WHAT IS DISTILLATION? DISTILLATION
Distillation is a process of separating the component substances from a liquid mixture by selective evaporation and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components of the mixture.
DISTILLATION
WHAT IS PAPER CHROMATOGRAPHY?
PAPER CHROMATOGRAPHY Paper chromatography is an
analytical method that is used to separate coloured chemicals or substances, especially pigments. This can also be used in secondary or primary colours in ink experiments. This method has been largely replaced by thin layer chromatography, but is still a powerful teaching tool.
PAPER CHROMATOGRAPHY
WHAT IS CENTRIFUGATION
CENTRIFUGATIONCentrifugation is a process
which involves the use of the centrifugal force for the sedimentation of heterogeneous mixtures with a centrifuge, used in industry and in laboratory settings. This process is used to separate two immiscible liquids.
