CA 2462540

The present invention relates to a froth flotation mechanism located in a flotation cell, comprising a directional element suspended from the lower end of a hollow shaft extending to the lower section of the cell and vertical vanes attached to said directional element, which extend above and below the directional element and horizontally beyond the directional element. The substantially horizontal circular plate of the directional element is symmetrically attached around the shaft at its centre and the outer edge of the central plate is bent downwards to form the lap of the guiding part. The gas spreading plate is located on the inner side of the lap. The flotation cell is comprised of a cylindrical lower section, a middle section located above it in the form of a truncated cone widening upwards, and a cylindrical upper section attached to the top of it.

L'invention concerne un mécanisme de flottation par mousse situé dans une cellule de flottation, comprenant un élément directionnel suspendu à l'extrémité inférieure d'un arbre creux qui s'étend jusqu'à la partie inférieure de ladite cellule, et des aubes verticales fixées audit élément directionnel s'étendant au-dessus et au-dessous dudit élément directionnel et horizontalement au-delà de celui-ci. La plaque circulaire sensiblement horizontale de l'élément directionnel est fixée de manière symétrique autour de l'arbre au niveau de son centre, et le bord extérieur d'une plaque centrale est courbé vers le bas afin de former un recouvrement d'une partie de guidage. Une plaque répandant le gaz est située sur le côté intérieur du recouvrement. La cellule de flottation est constituée d'une partie inférieure cylindrique, au-dessus de laquelle se trouve une partie intermédiaire sous forme de cône tronqué s'élargissant vers le haut, et d'une partie supérieure cylindrique fixée au dessus des deux autres parties.
