Systems and methods for cryogenic separation of plant material are provided. A vessel is filled with cryogenic fluid having a temperature at or less than −150 degrees Celsius. Plant material is placed into the vessel via a basket and agitation is provided to the plant material in the vessel for a predetermined time period. Upon completion of the time period, the basket having at least a portion of the plant material is removed from the vessel. Plant particulates separated from the plant material during the agitation settle to the bottom of the vessel. The vessel is drained of the cryogenic fluid, including plant particulates separated from the plant material.

A non-aqueous process for producing bitumen from oil sands is provided, and includes contacting oil sands and solvent to produce solvent diluted bitumen and solvent diluted tailings. The solvent diluted bitumen is subjected to a first fines separation stage that produces an overflow solvent diluted bitumen stream with residual fines that is subjected to a second fines separation stage to remove residual fines and produce a solvent diluted bitumen stream, which is subjected to solvent recovery. The fines streams are subjected to washing to produce washed tailings and solvent wash liquor comprising solvent and bitumen. Another non-aqueous process for producing bitumen from oil sands is provided, and includes subjecting oil sands to solvent extraction, including displacing the oil sands material and a solbit counter-currently and horizontally, and recovering a bitumen enriched solbit stream which is subjected to fines separation and subjecting the solvent diluted bitumen stream to solvent recovery.

A separation apparatus and method for separating ore is provided. The separation apparatus (10) includes a separation chamber (12) and is configured to be utilised with a fluid pulsing mechanism (32) for operatively pulsating a fluid through ore deposited in the chamber resulting in the migration of generally lighter ore particles toward an upper region (25) of the chamber and for generally heavier particles to migrate toward a bottom region (14) of the chamber (12). The ore is deposited by means of a chute (38) in the bottom region (14) of the chamber (12) and the lighter ore particles may then be extracted from the chamber through a first chamber outlet (24) while the heavier particles may be extracted through a second chamber outlet (28).
