Abstract:
Methods for drying oil sand fine tailings treated to comprise flocculated fine tailings, by deposition and farming techniques, are provided. A deposition cell is provided with a sloped bottom surface and the flocculated fine tailings are deposited to undergo channelless advancement in the cell while allowing drainage of release water. When the deposit is uneven, the deposit may be plowed while wet for spreading and ensuring water release conditioning is imparted thereto, while avoiding over-shearing, and maintaining sufficient shear strength to allow standing. Once a dried upper crust forms, the deposit may be harrowed to break up the crust, expose wet regions there-beneath and create furrows in the standing deposit. The methods improve the dewatering and drying of mature fine tailings in oil sands.
