Methods of Mixture Separation Flashcards
Mechanical Separation
(often by hand) takes advantage of physical property such as color and shape
What are some examples of Mechanical Separation?
recycling plastic, paper, metal
separating m&ms with a tweezer
What is Magnetic Separation?
takes advantage of
the physical property of magnetism.
What are some examples of magnetic separation?
separating metals in a scrap yard
separating sulphur and iron filings
Filtration
takes advantage of the physical property of the state of matter. A screen lefts liquid partilces through, but traps solid particles.
Examples of Filtration
filtering coffee, spaghetti,
What are some examples of filters?
a window screen, an air filter, a sand sieve
Decanting
To pour off a liquid, leaving another liquid or solid behind.
Takes advantage of differences in density.
Examples of decanting
water from rice
Distillation
The separation fo a mixture fo liquids based on the physical property of boiling point.,
Examples of distillation
the distillation of alcohol or oil; crude oil refining
Evaporating
Vaporizing a liquid and leaving the dissolved
solid(s) behind.
Used to separate salt solutions.
Examples of evaporation
Obtaining sea salt from sea water evaporation ponds
Density Separation
More dense components sink to the bottom and less dense components float. The components cannot be coluble with each other,
Centrifuge
Circular motion helps denser components sink to the bottom faster
