CA 2332207

Processes and apparatuses for recovering an oil-enriched product from an oil-bearing material such as tar sand ore are disclosed. One such process includes mixing the oil-bearing material with solvent to form a slurry in a slurry feed tank, and pumping the slurry into a hydrocyclone to separate it into an overflow portion and an underflow portion, the overflow portion containing the oil-enriched product. The process further includes vacuum filtering the underflow portion to remove solvent therefrom and produce substantially dewatered tailings, recycling the solvent removed from the underflow portion back into an earlier stage of the process, and adding fresh solvent into the process.
