A method of separating non-oil sand substances and oil sands in extracted material is provided. The method has the steps of, in a pelletizing section of a pelletizer, forming the extracted material into pellets, cooling the pellets in a cooling section of the pelletizer, the cooling section receiving the pellets from the pelletizing section such that the pellets are separated, the cooling section cooling at least a surface of the pellets sufficiently to prevent the pellets from aggregating, the pellets having a specific gravity based on their composition, stratifying the pellets in a fluidized bed according to specific gravities, the fluidized bed receiving the pellets from the pelletizer, and removing pellets having a desired specific gravity from the fluidized bed through pellet outlets at spaced locations in communication with the fluidized bed. |
