1) separating salt and water
2) separating sugar and water
exaples
evaporation is a kind of separation method it is used for separating a dissolved solid (solute) from a liquid
during evaporation a substance that is dissolved in the liquid is left back and the liquid goes into air. So evaporation is used as a seperation technique.
Distillation
Winnowing
These separation methods are not suitable for compounds; they are used for mixtures.

Examples: decantation, sieving, magnetic separation.

EVAPORATION
Separation techniques are those techniques that can be used to separate two different states of matter such as liquid and solid. Such separation techniques include filtration or evaporation.

when do we use method of separation? Let us describe it with an example. Let there be an time dependent schodinger eqn containing wave fn (which depends upon position and time),the k.E.term and the potential energy term.The wave fn can be written as a separation of variables i.e S(r,t) =A(r)B(t) when the potential is independent of time.

Distillation
Distillation, filtering, sifting, and evaporation.
