ABSTRACT:
A continuous process for extraction of bitumen from oil sand by a hydrocarbon solvent wherein the sand is classified so as to produce a major coarse fraction and a minor fines fraction, with both fractions contacted with solvent to wash miscella therefrom, and wherein the major coarse fraction is contacted with solvent by gravity percolation and the classification of the sand is effected to remove sufficient fine material to achieve a flooding rate in the gravity percolation of between 1 and 4 gallons per minute per square foot.
