Abstract
Méthode permettant de compacter des solides sur place dans un bassin de résidus d'extraction de sables bitumineux. La méthode comprend les étapes suivantes : disposer deux électrodes ou plus dans le bassin de résidus, selon un espacement prédéterminé; et raccorder les électrodes à une source d'énergie à tension variable. Cela crée au moins une cathode et au moins une anode de même qu'un champ électrique entre les deux. Le champ électrique est d'une force suffisante pour induire la floculation des particules dans les résidus et pour libérer de l'eau, simultanément. Ensuite, les solides subissent un autre compactage et davantage d'eau est libérée, pour créer un matériau solide présentant une force portante minimale souhaitée. Selon un autre mode de réalisation, une électrode utilisée pour mener à bien la méthode est présentée.
