The process is called separation.
DISTILLATION
It is called distillation
Two mixtures can be seperated using evaporation cause they have diffrent boiling points.The process is call distillation,one mixture will boil and evaporate leaving the other in the flask.Therefore separating the two mixtures.
This method is called paper chromatography.
You think probable to a chromatographic method or to decantation.
by separating it
There are several different ways and procedures of separating mixtures, though, some mixtures areirreversible, and can permanently be combined. A few ways of separating mixtures is through evaporation, filtration, sieving, gravity separation, distillation, condensation, froth flotation, magnetic separation, chromatography, and centrifuging (http://www.slideshare.net/brittgow/separating-mixtures-1247457). Also certain chemical reactions can separate mixtures, or create substances, i.e. acid+base=salt+water etc. (If this is no help I'm sorry just look up separating mixtures on Google).
Using the separating funnel method can be separated mixtures of liquids with different densities.
evaporation and filtering
oil and water
MItosis
this process would be called diffusion
