A method and a system for removal of Mature Fine Tailings (MFT) out of oilsands tailings ponds, specifically enabling year-round removal of MFT which density is greater than 1.35 t/m3. It utilizes a hollow, essentially fully enclosed around its perimeter, ideally of cylindrical form structure, (henceforth called the "structure") (5) of predetermined geometry, which is placed at the pond surface as shown in Figure 2. Water and less dense MFT initially located within the structure is moved outside the structure, while the MFT of required density which is surrounding the structure enters it under the action of hydrostatic pressure as per Figure 6. Continuous MFT removal operation is enabled due to simultaneous inflow of MFT surrounding the structure so that the hydrostatic equilibrium as per Formula 1 noted herein is maintained. |
