A method of extracting bitumen from oil sands haung a transition temperature at which the oil sands solidif/ includes forming formable oil sands into pellets and cooling at least a surface of the pellets sufficienth to pre/ ent the pellets from aggregating, cooling the pellets to below the transition temperature, fracturing the pellets to release the bitumen from the oil sands while maintaining the temperature of the pellets below the transition temperature, and separating the bitumen from the oil sands in a separator. |
