Abstract:
A process for extraction of bitumen and other oil products from sand, other sedimentary deposits and from mine tailings, may comprise flowing solvent through these bitumen-containing materials held in a filter press, where elevated pressures and temperatures may be used. After exposure to solvent the sedimentary deposits may be exposed to hot water, steam and/or vacuum to remove residual solvents. Further embodiments of the bitumen extraction process may include substituting the solvent with hot water or steam. Filter press systems for extracting bitumen are also described.
