摘要： The invention relates to methods for drying oil sand fine tailings treated to comprise flocculated fine tailings, by deposition and farming techniques. 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, it may be plowed 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.

摘要： The present invention generally relates to the field of treating oil sand fine tailings. A process for drying fine tailings, which may use a pipeline reactor system, comprises providing an in-line flow of the fine tailings; continuously introducing a flocculent solution to cause dispersion and commence flocculation of the fine tailings and may comprise rapid turbulent mixing; subjecting the fine tailings to flocculation and water release conditioning in-line to cause formation and rearrangement of flocs and increasing the yield shear stress to form flocculated fine tailings while avoiding over-shearing of the flocs; and depositing the fine tailings to allow the release of water, formation of a non- flowing fine tailings deposit and drying of the non-flowing fine tailings deposit. The process enables effective in-line dispersion, flocculation and water release, resulting in reliable deposition and drying of the fine tailings deposit.
