Abstract

Linvention concerne un procédé pour le traitement sur place de résidus dans une zone de confinement ayant une couche de résidus comprenant des solides fins et de leau, consistant à : ajouter un floculant, un coagulant, un agent modificateur dhydrophobicité ou toute combinaison de ceux-ci, dans une partie de la couche de résidus; mélanger la partie de la couche de résidus et un floculant, un coagulant, un collecteur ou des combinaisons de ceux-ci, pour former des résidus traités sur place; et laisser les résidus traités sur place sassécher et/ou se consolider sur place dans la zone de confinement des résidus.
