Decantation
Decantation is a process for the
separation of mixtures, carefully pouring a solution from a container, leaving the
precipitate (
sediments) in the bottom of the container. Usually a small amount of solution must be left in the container, and care must be taken to prevent a small amount of precipitate from flowing with the solution out of the container. It is generally used to separate a liquid from an
insoluble solid, e.g. in red
wine, where the wine is decanted from the
potassium bitartrate crystals. Another example is when separating the oil from water after getting them as a mixed liquid out of olives in order to extract olive oil.

Décantation
La décantation est une opération de séparation mécanique, sous l'action de la
gravitation, de plusieurs
phases non-
miscibles dont l'une au moins est liquide. On peut ainsi séparer soit plusieurs liquides non-miscibles de densités différentes, soit des solides insolubles en suspension dans un liquide.
