Abstract
Official abstract text for this publication.
A method for controlling the solids distribution in a bitumen froth produced when processing an oil sands ore having a d50 of about 250 μm or greater and a d90 of about 450 μm or greater is provided comprising adding a high-fines material having a d50 of about 50 μm or less and a fines content of about 40% of the solids or greater to the oil sands ore to form an ore blend; and processing the ore blend in a water-based bitumen extraction process to produce the bitumen froth.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for controlling the solids distribution in a bitumen froth produced when processing an oil sands ore having a d 50 of about 250 μm or greater and a d 90 of about 450 μm or greater, the method comprising the steps of: adding a waste material having a bitumen content less than 6 wt %, a d 50 of about 50 μm or less and a fines content of about 40% of the solids or greater to the oil sands ore to form an ore blend; and processing the ore blend in a water-based bitumen extraction process to produce the bitumen froth. 2. The method as claimed in claim 1 , wherein the bitumen froth has a d 50 of less than about 35 μm. 3. The method as claimed in claim 1 , wherein between about 5 wt % and about 30 wt % of the waste material is added to the oil sands ore. 4. The method as claimed in claim 1 , wherein the waste material has a fines content of 50% of the solids or greater. 5. The method as claimed in claim 1 , wherein the waste material has a fines content of 60% of the solids or greater. 6. The method as claimed in claim 1 , wherein the waste material has a fines content of 70% of the solids or greater. 7. The method as claimed in claim 1 , wherein the waste material has a fines content of 80% of the solids or greater. 8. The method as claimed in claim 1 , wherein the waste material is selected from the group consisting of overburden, interburden, pond mud, below cut-off grade ore and oil sand tailings. 9. The method as claimed in claim 8 , wherein the oil sand tailings are Fluid Fine Tailings (FFT). 10. The method as claimed in claim 9 , wherein the FFT are Mature Fine Tailings (MFT). 11. The method as claimed in claim 8 , wherein the waste material is below cut-off grade ore.
