Abstract:
1. A method for drying fine tailings, comprising: providing a deposition cell comprising: a head region; a toe region spaced away from the head region; and a sloped bottom surface extending from the head region to the toe region such that the toe region is at a lower elevation than the head region; depositing flocculated fine tailings at the head region of the deposition cell, to form a deposit that undergoes buildup and moves down the sloped bottom surface, the deposit forming a built-up area and a lower area; and plowing the deposit while wet to spread the modified fine tailings from the built-up area toward the lower area, to ensure water release conditioning while avoiding over-shearing and maintaining sufficient shear strength of the flocculated fine tailings to allow standing.
