Title Method of removing bitumen from tar sand for subsequent recovery of the bitumen
Date 1977-10-18
Description A method of removing bitumen from tar sand for subsequent recovery of the bitumen. The method comprises submerging tar sand in a sufficient amount of a circulating solvent in which the bitumen is soluble, and, while the tar sand is so submerged, sonicating within the solvent with a sufficient amount of sonic energy to break apart any connections between sand granules and to remove bitumen from the sand granules to thereby permit the bitumen so removed to go into solution in the solvent for subsequent removal of the solvent-plus-bitumen and recovery of the bitumen therefrom.
