Enhanced techniques for dewatering thick fine tailings

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.

Dehydration and Disintegration Apparatus and System
20200398284 · 2020-12-24 ·

There is disclosed an apparatus 100 for reducing the size of a solid material into smaller particles including powder form comprising: an implosion chamber 3 for containing the solid material; and adapted for creating turbulence and ultrasonic soundwaves that bounce off the chamber walls at different angles to create sound frequencies of varying patterns; causing the expansion of moisture particles in the solid material leading to implosion of moisture particles within the solid material. The implosion thereby results to cavitation and reducing the size of solid material within the chamber 3 into smaller particles; a separating section A for separating the particles based on sizes; and channelling the coarser particles into the chamber to go through additional disintegration process; the implosion chamber 3 comprises a conical member 14, a static propeller 9 attached to at least one surface of the chamber 3 and a flail propeller 13 rotatably below the conical member 14 and static propeller 9; the flail propeller 13 and the conical member 14 being connected to an axis within the chamber 3. The rotation of the flail propeller 13 within the chamber 3 generating ultrasonic soundwaves that causes the moisture particles of the solid material to oscillate at high frequency and expansion that disintegrates the solid material. During this process, the moisture content is converted into vapour.
