Abstract

The Invention relates to a flotation machine (1) which at least consists of a flotation cell (2) having a means for feeding slurry in the flotation cell, a gas dispersion mechanism (3) for feeding gas into the slurry and producing froth, a means for removing froth from the flotation cell and a means for removing tailings from the flotation cell, when there is arranged at least one guiding device (4) near the gas dispersion mechanism (3) in order to guide the dispersed gas (5) away from the gas dispersion mechanism (3).
