Chemistry for Kids: Separating Mixtures Ducksters
The filtration process is generally used to separate a suspension mixture where small solid particles are suspended in liquid or air. In the case of filtering water, the water is forced through a paper that is made up of a very fine mesh of fibers. The water that has been run through the filter is called the filtrate.

New separation technique for waste plastics ScienceDirect
New separation cell A flotation cell for plastics must simultaneously satisfy the following conditions: (1) Air bubbles of the most suitable size for flotation of plastics must be uniformly generated in the flotation cell. (2) Agitation to avoid sedimentation of large particles. (3) No turbulent water flow generated in the separation zone.

Lab #2 PHYSICAL SEPARATION TECHNIQUES Introduction
original mixture. The separation scheme used to separate the mixture is based on differences in the physical properties (such as boiling point, melting point, solubility in a given solvent, etc.) of the three components. Chemists frequently illustrate a separation procedure by means of a flow chart as depicted below.

The mixtures are separated into their components for various purposes such as : (1) To remove an undesirable component, We make a cup of tea by boiling tea leaves in water and then adding sugar and milk. Used tea leaves are an undesirable component of the mixture called tea. These are separated by using a filter called tea strainer.

Separation by Centrifugation GeeksforGeeks
Centrifugation is a mechanical technique for separation which involves the usage of the centrifugal force to separate particles contained in a particles are segregated depending on their size, shape, density, and rotor speed. The suspended particles in a mixture are rotated at a high speed in a machine, called the centrifuge in order to segregate the particles from the liquid.

separation and purification Filtration and screening | Britannica
Filtration and screening. In filtration, a porous material is used to separate particles of different sizes. If the pore sizes are highly uniform, separation can be fairly sensitive to the size of the particles, but the method is most commonly used to effect gross separations, as of liquids from suspended crystals or other solids. To accelerate ...

separation and purification | Definition, Technology, Methods, Facts
There are two general reasons for performing separations on mixtures. First, the mixture may contain some substance that should be isolated from the rest of the mixture: this process of isolating and thus removing substances considered to be contaminants is called purification.

Separation of Mixtures Using Different Techniques (Procedure) : Class 9 ...
Fix a separating funnel in a stand. Pour about 50ml of a mixture of oil and water through a filter funnel into a separating funnel. Close the separating funnel using a lid. Take the funnel from the stand and invert it. Now shake the funnel gently and slowly. Now, open the stopcock of the separating funnel to release the pressure inside the funnel.

Centrifugation a centrifuge will separate mixtures based on their mass. The mixture is placed in a centrifuge tube which is then spun at a high speed. Heavier components will settle at the bottom of the tube while lighter components will be at the top. This is the technique used to separate red blood cells from blood plasma.

Magnetic Separation Method Mineral Processing Metallurgy
Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics", those ...
