Abstract:Evaporation and freeze-thaw phenomena are known to contribute to dewatering and densification of fine tailings streams generated from oil sands bitumen extraction.This thesis reports on studies of 1-Dimensional freezing of polymer-amended mature fine tailings that have different stress histories with respect to degree of desiccation by evaporation and self-weight consolidation. Freezing is accomplished using an electric cooling plate specially mounted in an insulated column. Polymer-amended tailings are placed… Show more
