Abstract
A modified paraffinic froth treatment (PFT) process is described, in which a fine tailings stream obtained from a water extraction process practiced on oil sands is added during the treatment process. This modified process may be useful as a treatment for the fine tailings stream, allowing for the flocculation of the fines, thus reducing the volume of such fine tailings. The modified process may also be useful in that the fine tailings stream can be used as a supplement or a replacement for dilution water, thus eliminating or reducing the need for dilution water in the PFT process.
