ABSTRACT: The main purpose of this research was to understand the segregation behaviour of uranium tailings. Historical borehole data from the Deilmann Tailings Management Facility (DTMF) at Key Lake, Saskatchewan exhibited segregation within a narrow range of ± 2% when scaled to the average solids content. Similarly, laboratory investigations on various ore types indicated that uranium tailings are mainly silty-sand type materials and remain non-segregating when the solids content is between 25% and 40% at the onset of deposition.

RÉSUMÉ: Le but principal de cette recherche était de comprendre le comportement en terme de ségrégation des déchets des mines d'uranium. Les données historiques de forage à partir de l'installation de Deilmann à Key Lake, Saskatchewan montrent une ségrégation au sein d'une gamme étroite de ± 2%. De même, les investigations en laboratoire sur divers types de minerai ont indiqué que les résidus des déchets de mines d'uranium sont principalement les matériaux de type sable fin et restent sans ségrégation lorsque le contenu en matières solides est entre 25% et 40% quand la déposition commence.
