  • Publication number: 20200123030
    Abstract: Various techniques are provided in relation to flocculation and/or dewatering of thick fine tailings, with shear conditioning of flocculated tailings material in accordance with a pre-determined shearing parameter, such as the Camp Number. One example method of treating thick fine tailings including dispersing a flocculant into the thick fine tailings to form a flocculating mixture; shearing the flocculating mixture to increase yield stress and produce a flocculated mixture; shear conditioning the flocculated mixture to decrease the yield stress and break down flocs, the shear conditioning being performed in accordance with the pre-determined shearing parameter to produce conditioned flocculated material within a water release zone where release water separates from the conditioned flocculated material. The conditioned flocculated material can then be subjected to dewatering, for example by depositing, thickening or filtering.

  • Publication number: 20190352207
    Abstract: A process for the treatment of thick fine tailings that include constituents of concern (CoCs) and suspended solids is provided. The process includes subjecting the thick fine tailings to treatments including chemical immobilization of the CoCs, polymer flocculation of the suspended solids, and dewatering. The chemical immobilization can include the addition of compounds enabling the insolubilization of the CoCs. Subjecting the thick fine tailings to chemical immobilization and polymer flocculation can facilitate production of a reclamation-ready material, which can enable disposing of the material as part of a permanent aquatic storage structure (PASS).

  • Publication number: 20190163218
    Abstract: The present invention provides a new method and apparatus for receiving signals containing information about a plurality of velocity profiles of a flow in a pipe and about a pressure gradient of the flow over a length of the pipe; and determining information about an injection of a chemical into the flow in the pipe based at least partly on the information contained in the signals.

  • Patent number: 10071352
    Abstract: Apparatus is provided featuring a signal processor or processing module configured at least to: a signal processor configured to: receive signaling containing information about at least one rheological parameter related to a fluid containing Mature Fine Tailings (MFTs) flowing through a process pipe; and determine a dosing of a polymer to the fluid so as to cause a polymer induced agglomeration of the MFTs in the fluid, based at least partly on the signaling received. The signal processor may be configured to provide corresponding signaling to control the dosing of the polymer to cause the polymer induced fine agglomeration of the MFTs in the fluid.

  • Publication number: 20170267558
    Abstract: Techniques are described that relate to enhancing flocculation and dewatering of thick fine tailings, for example by reducing process oscillations. One example method includes dispersing a flocculant into thick fine tailings having a turbulent flow regime to produce turbulent flocculating tailings; subjecting the turbulent flocculating tailings to shear to build up flocs and increase yield stress, to produce a flocculated material having a non-turbulent flow regime; and shear conditioning the flocculated material to decrease the yield stress and produce conditioned flocculated tailings within a water release zone; and dewatering the conditioned flocculated tailings, for example by employing sub-aerial deposition. The thick fine tailings may have a Bingham Reynolds Number of at least 40,000 upon flocculant addition.

  • Patent number: 9404686
    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.

  • Publication number: 20150203385
    Abstract: Techniques for injecting gas, such as compressed air, into thick fine tailings can promote water release or flocculant dosage reduction and thereby ameliorate dewatering operations of the thick fine tailings. Gas injection may be done before, during or after addition of a polymer flocculant into the thick fine tailings. Gas injection may be done in an amount, pressure or with gas bubbles so as to reduce the flocculant dosage requirements or increase the water release from released thick fine tailings.
