ABSTRACT:
Flotation apparatus and methods for separating particles from particulate suspensions such as coal and mineral ore slurries, wherein fluid discharge is removed annularly from a flotation vessel. Preferably, the flotation apparatus includes a vertically oriented, cylindrical flotation vessel having a tangential inlet at its upper end and an annular outlet at its lower end. The annular outlet allows for the smooth exit of fluid discharge from the flotation vessel so as to avoid disturbance of the fluid flow within the flotation vessel. The apparatus includes a froth pedestal positioned within the lower end of the vessel which forms the annular outlet with the wall of the vessel. The froth pedestal further serves to support a froth column formed within the flotation vessel and isolates the froth column from the fluid discharge so as to minimize mixing therebetween.
