Abstract
Méthode de traitement de déchets miniers. La méthode consiste à former un flux floculé en ajoutant un premier floculant à un flux de déchets dérivé de lextraction du bitume, à laide dun procédé à base deau, contenu dans des sables bitumineux. Le flux de déchets comprend des particules fines et des solides. Le flux floculé est transporté vers un site de dépôt. Dautre part, un flux refloculé est formé par lajout dun deuxième floculant au flux floculé, après le transport du flux floculé. Le flux refloculé est déposé dans une zone de dépôt du site de dépôt. Le premier floculant et le deuxième floculant comprennent un polymère non ionique et un polymère anionique.
