Abstract
An extraction system and process for extracting bitumen from a slurry containing bitumen, solids and water. The system comprises a cyclone separation facility for separating the slurry into a solids component stream and a bitumen froth stream with the bitumen froth stream including water and fine solids. The bitumen froth stream is then delivered to a froth concentration facility for separating the bitumen froth stream into a final bitumen enriched froth stream, and a water and fine solids stream. The final bitumen enriched froth stream is suitable for further processing. The system of the present invention is preferably mobile so that the cyclone extraction facility and the froth concentration facility can move with the mine face at an oil sands mining site, however, it is also contemplated that the system can be retrofitted to existing fixed treatment facilities to improve the operational efficiency of such fixed facilities.
