    Oil bearing sands recovery process comprising a main separation stage. The oil bearing sands is slurried in the main separation stage with water to produce an enriched fraction and a dilute aqueous clay waste. The aqueous clay waste is sedimented in a waste sedimentation stage in one or more settling lagoons to provide a substantially solid clay sediment and supernatant

    The alumina plant discharges red mud in a slurry of 25–30% solids, and this also presents an opportunity to reduce disposal volumes. Today’s technology, in the form of high-efficiency deep thickeners, and large-diameter conventional thickeners, can produce a mud of 50–60% solids concentration. The lime used in the process forms insoluble

Coal-clay waste slurry was dewatered from a nominal 7 percent solids to greater than 50 percent solids using 0.3 to 0.5 pound of 8-million-molecular-weight PEO per ton. Solution concentrations ranged from 0.025 to 0.25 percent PEO
