Abstract: A method for monitoring dewatering of flocculated oil sands tailings involves positioning an image capture device in a flow of flocculated oil sands tailing through a pipeline for acquiring images of the flocculated oil sands tailings; collecting the images of the flocculated oil sands tailings; and analyzing the one or more images to ensure production of optimum floc structures for maximum oil sands fine tailings dewatering.

Abstract: A subject of the invention is a folding barrier device comprising a parallelipipedic box (100) constituted by a base (106) having the shape of a parallelogram, with a long side (the length of the box) and a short side (the width of the box), 2 side walls (102, 104) having the shape of a parallelogram, with a length equal to the length of the long side of the box, therefore of the base, and a width equal to the height of the box, said walls being capable of preferably having a rectangular shape, linked to the base by their long side, and equipped with a lid (101) having the shape of a parallelogram, of at least the same dimensions as the base of said box, said lid being hinged so as to pass between a position horizontal to and a position vertical to one of the 2 walls constituting one of the long sides of said box, said box containing at least one folding barrier (107) constituted by a handrail (109) and bars (108), said bars being hinged by means of hinges at one of their ends (upper end) to a handrail
