Abstract

Un procédé d'assèchement de résidus est présenté comprenant le mélange des résidus avec une quantité suffisante dun additif ou dun mélange d'additifs; le dépôt du mélange résultant dans une zone délimination; le pompage de l'eau du dépôt vers une ou plusieurs pompes submersibles et lattente de l'atteinte dune concentration suffisante du dépôt, et lextraction de leau de dépôt et des eaux de pluie restant dans le dépôt au moyen dun ou de plusieurs dun réseau de fossés, une tour de décantation ou une pluralité de structures de digue pour permettre à un dépôt non ségrégé dêtre réhabilité.
