摘要： 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. The design, construction and/or operation of a flocculation pipeline assembly can be facilitated.

摘要： 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. Inhibiting process oscillations may include providing turbulent tailings feed, configuring a downstream pipeline assembly to reduce backpressure fluctuations and/or reducing air content in the flocculant solution, for example.
