Title: Enhanced techniques for dewatering thick fine tailings with flocculant dosing on clay basis
Inventor: REVINGTON ADRIAN
IPC: C10G1/04
Filed: 2017-12-06
Granted: 2020-02-20
Abstract: Techniques for dewatering thick fine tailings may include one or more pre-treatment steps, such as pre-shearing to reduce the yield stress prior to flocculation, hydrocarbon removal below a threshold to improve flocculation and dewatering, flocculant dosing on a clay basis, and providing certain properties of the thick fine tailings related to coarse and fine particle sizes and/or chemistry such as divalent cation content. Various advantages may result from pre-treatments based on thick fine tailings properties, such as reduced flocculant dosage requirements, improved dispersion of flocculant into the thick fine tailings and/or enhanced dewatering, for example. One or more of the pre-treatments may be performed.
