    Abstract: A process for drying fine tailings is provided. The process, 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 floes 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.

    Abstract: A method and device for in-line injecting of flocculent agent into a fluid flow of mature fine tailings (MFT). The method includes the steps of: a) providing a fluid flow of mature fine tailings to be treated along a given channel fluidly connected to the pipeline; b) providing a source of flocculating agent; and c) introducing flocculating agent inside the fluid flow of mature fine tailings via a plurality of injection outlets for injecting the flocculating agent into the fluid flow in a dispersed manner so as to increase an exposed surface area of the injected flocculating agent and thus increase a corresponding reaction with the mature fine tailings, for an improved flocculation of said mature fine tailings, and/or other desired end results. Also disclosed is a kit with corresponding components for assembling the in-line injection device to be connected in-line with the pipeline carrying the mature fine tailings to be treated.
