METHODS FOR EXTRACTING BITUMEN FROM BITUMINOUS MATERIAL |
摘要 |
Methods for preparing solvent-dry, stackable tailings. The method can include the steps of adding a first quantity of solvent to a bitumen material to form a first mixture, separating a first quantity of bitumen-enriched solvent from the first mixture and thereby creating solvent-wet tailings, and adding a quantity of water to the solvent-wet tailings to separate a solvent component from the solvent-wet tailings and thereby forming solvent-dry, stackable tailings. The solvent used in the methods can include paraffinic solvent, such as pentane.
