Oil Sand - Tailing pond dredging - The standard industry practice is to pump oil sands tailings into large settling ponds. There, the heaviest material settles to the bottom, separating from the top layer of water which can be recycled.
Oil sands tailings are a mixture of water, clay, sand and residual hydrocarbons produced during the mine extraction process. The middle layer of the pond, known as mature fine tailings (MFT), could take centuries to solidify.As mining operations expands it is necessary to build more and larger settling ponds. Finding a way to get out from the pond the MFT and quickly transform into a soil-like deposit suitable for reclaiming is critical to improving overall reclamation performance.
