摘要： Described herein, is a method of dewatering a slurry, the slurry being tailings from bitumen extraction of mined oil sand. The slurry is passed through at least one electro-kinetic thickener having a voltage gradient to separate water from the slurry to produce a dewatered slurry. The electro-kinetic thickener may comprise an auger to move the slurry downstream. The auger has a conductive component in the form of a wire, ribbon or rod as an anode (positive electrode) to attract negatively-charged slurry particles and to repel the positively-charged cations and associated water. The auger is shafted or shaftless. The electro-kinetic thickener may also comprise a porous drum having the auger disposed therein. The porous drum is a cathode (negative electrode) to repel the negatively-charged slurry particles, attract the positively-charged cations and associated water, and allow the water to pass through the porous drum.
