Abstract
Relocatable systems and processes for processing oil sands are described. Relocatable components are employed to permit oil sand processing to be conducted near a mine face, and relocated as the mine face recedes. Flow of the slurry in combination with appropriate water injection through the relocatable pipeline causes agglomeration of fines within the slurry. Bitumen/solvent mixtures can be filtered from the agglomerates within downstream solvent extraction system components. A high quality bitumen product is formed, having water and solids content that exceeds downstream processing and pipeline requirements. Dry tailings may be back-filled in-pit.
