Abstract
L'invention concerne un procédé de traitement d'un courant de résidus qui contient de l'eau et des solides tels que du sable et de l'argile, le procédé comprenant les étapes suivantes : (i) ajouter un ciment au courant de résidus ; et (ii) séparer au moins une partie du ciment et des solides du courant de résidus. Le procédé peut aussi comprendre l'ajout d'un ou plusieurs coagulants ou floculants au courant de résidus.
