ABSTRACT OF THE DISCLOSURE The invention relates to a process for the conditioning of oil sands to increase the amount of high fines reject to permit separation of the oil sands into a high fines fraction comprising 5 to 25 % of the feed and a low fines fraction comprising 95 to 75 % of the feed. Having separated the feed in this manner, a hybrid Hot Water Extraction/Anhydrous Extraction process may be advantageously employed to extract bitumen from the low fines and high fines fractions, respectively.
