Apparatus for use in froth flotation comprising at least four parallel upright partition walls defining flotation columns within a receptacle. Below each partition wall is a froth generator driven by a shaft passing through the thickness of the partition wall. Rods of differential buoyancies divide each flotation column into flotation cells in such a way as to permit froth to pass upwardly from one cell to another in a controlled manner maintaining a predetermined froth thickness in each cell. |
