Observed the Techniques for Separating1. Decantation
Decantation is a method of separation between a solution and the simplest solid by pouring the liquid slowly until the precipitate remains at the bottom of the vessel. Examples of decantation are:
- Water and sand
- Water and oil
- Separation of Glycerin from Biodiesel
- Mercury Decontamination
- Vinegar Making
- Water purification
- Wine decantation
- Oil refining.
- Juice preparation.
2. Evaporation
Evaporation is a type of evaporation process that occurs in liquids. Evaporation occurs when a liquid on the surface turns into a gas or vapor. Evaporation occurs when a liquid is heated. That is, the liquid molecules must gain kinetic energy. As the liquid molecules gain kinetic energy, the molecules start to spread out and vibrate faster. This causes the liquid to change from a liquid to a gas. The examples:
- Evaporate seawater to get salt
- Heating water
3. Filtration
Filtration is a physical separation method or better known as filtration which is carried out to separate solids and liquids. The way it works is by pouring the mixture from above into the filter media and in the presence of gravity forcing the liquid to be attracted to the bottom. That way the solids will remain in the filter. The examples:
- Brewing coffee
- Make tea, we have to throw away the dregs
- Separating sand from water
4. Sieving
Sieving is a mechanical method of separating materials or particles based on differences in particle size. The examples:
- Sift the flour
- Sort the harvested fruit by its size
5. Using Magnet
A combination of components can be separated via magnetic separation. In the illustration, two substances in the mineral ore—one magnetic and the other non-magnetic—are being separated. The example:
- Separate iron from a mixture of sand
- Recycling facilities frequently use magnetic separation to isolate metals
- Removing iron-bearing particles from the glass-making silica sand
