MIXTURE SEPARATION METHODS
Filtration:
In this technique, suspended solid fragments are extracted from a liquid. This only occurs when the solid fragments are larger in diameter than the pores of the filter paper.
Flotation:
This method allows mixtures of similary sizes solids to be separated by density. For the method to work, the density of one of the two components must be lower than the density of water, while the remaining components must sink in water.
Distillation:
This method allows solutions of liquids with different boiling points to be separated. The mixture is heated until the liquid with a lower boiling point evaporates. The gas is collected and cooled, and is condensed in another container.
Leaching:
This method allows the separation of mixtures of solid components must be solube in liquid.
Centrifuging and decantation:
is the method of separating the components of a suspension or a liquid collodid according to their density by spinning at a high velocity.
Decantation:
A separation funnel allows the liquid components of heterogeneous mixtures with different densities to be separated.
Magnetic Separation:
When applied to a heterogeneous mixture of solids, this method allows the components with magnetic properties to be separated from the rest of the components.
There are diferents methods.
Sedimentation and decantation:
The technique based of the difference of densities, allows the components of a suspension to be separated.It involves allowing the mixture to sand until the solid and liquid components separate into two clearly different layers.
Chromatography:
This technique allows the components to be separated according to the speed at wich they travel through an absorbent suface, such as a piece of paper.
Vaporitzation:
This method is used to separate solutions of solids in a liquid solvent. After heating the mixture, the liquid is vaporitzed, The solid deposited at the bottom of the container is then recoverd.
Heterogenius mixtures
Homogenus mixtures
Sieving
: Allows mixtures of solids of different sizes to be separated. To do this we need a tool called sieve.
