  • Flocculation of lime-treated oil sands tailings

    Whole oil sands tailings resulting from water-based bitumen extraction processes can be co-flocculated, after treatment with slaked lime, with low dosages of a high molecular weight anionic polyacrylamide. The resulting composite sand-clay particles settle and dewater rapidly to a stackable product that can be hand-squeezed to 40–83 wt% solids.Tailings Management : Renova Foundation,One is that there are no single solutions given the extent and geographical diversity of the impact. The other concerns the existence of situations where the removal generates greater risk and damage than the stabilization or local treatment of the tailings. The Tailings Management Plan was developed based on these findings. Approved in June
