Abstract: A non-aqueous extraction process for producing a bitumen product from an oil sands material that includes an ablation stage is provided. The ablation stage can include adding an ablation solvent to an oil sands material to achieve a solvent-to-ore ratio of less than about 10, mixing the ablation solvent and the oil sands material to reduce the size of the oil sands material and produce ablated ore that includes ablated ore fragments having a diameter of less than about 2 inches, and retrieving the ablated ore as a single stream. The ablated ore can be subjected to a reject separation stage to separate reject material therefrom. The reject material can also be subjected to a wash reject stage. The ablated ore can then be subjected to an extraction stage. Examples of ablators are also described, which can include for instance a conveyor, or can be a rotary screen ablator.
