- 1SievingSieving is defined as a method in which two or more components of different sizes are separated from a mixture on the basis of the difference in their sizes. Ex: gravel and sand
- 2EvaporationEvaporation is one of the two forms of vaporization. It is the process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the gaseous state. Ex: salt water to keep just the salt.
- 3DistillationDistillation is the technique of heating a liquid to create vapor which is collected when cooled separate from the original liquid. It's based on the different boiling point or volatility values of the components. Ex: purification of alcohol.
- 4DecantationDecantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. Ex: oil and vinegar
- 5CrystallizationCrystallization is defined as a process by which a chemical is converted from a liquid solution into a solid crystalline state. Ex: snowflakes
- 6FiltrationFiltration is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass through but not the solid. Ex: coffee maker
- 7MagnetismMagnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials, it separates magnetic matter from non-magnetic matter. Ex: mining iron
- 8Paper ChromatographyPaper chromatography, in analytical chemistry, technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper. Ex: separating carbohydrates
- 9CentrifugingCentrifugation is sedimentation of particles under the influence of the centrifugal force and it is used for separation of superfine suspensions. Ex: blood cells from plasma cells.
