The invention relates to a method of separating substances according to which a substance containing at least a first and a second component are introduced, together with a wash fluid, into a container having at least one settling chamber and subjected to a gravitation field. Under the effect of the gravitation field the first substance component is concentrated in the settling chamber in a settling zone which is limited by a base. Next the substance containing said concentrated first component is evacuated from the settling zone through an opening in the base in the form of a sediment layer. The wash fluid flows against the sediment layer from the side and then passes through said sediment layer such that the remaining second component is at least partly displaced from the sediment layer. The invention also relates to a device, notably for carrying out the above method.
L'invention concerne un procédé permettant de séparer des matériaux. Selon le procédé, un matériau comprenant au moins un premier composant et un second composant, ainsi qu'un fluide de lavage, est introduit dans un récipient comportant au moins une chambre de sédimentation, puis soumis à un champ gravitationnel; dans la chambre de sédimentation, sous l'influence dudit champ gravitationnel, le matériau est enrichi en premier composant dans une zone de sédimentation délimitée par une base; le matériau enrichi en premier composant sort, sous forme de couche de sédiment, par une ouverture creusée dans ladite base; puis le fluide de lavage entre latéralement en contact avec la couche de sédiment et la traverse, de façon à déplacer de ladite couche, au moins partiellement, le second composant restant. L'invention concerne également un dispositif qui permet notamment de mettre en oeuvre ledit procédé.
