Beschreibung
Zusammenfassung:	The nozzle (1) has a tubular mixing arrangement (3) comprising an inlet zone for gas (7) and liquid (6) or suspension (6') and an outlet zone (1a) for a gas- or liquid mixture (8). The mixing arrangement is adjoined at a gas supply nozzle part (2), which is tapered in a direction of the mixing arrangement, and opens into the inlet zone. The mixing arrangement comprises an inlet opening (4) for the liquid in the inlet zone. A ratio of diameter of a gas outlet opening (2a) of the gas supply nozzle and internal diameter of the mixing arrangement in the inlet zone is in a range from 1:3 to 1:5. Independent claims are also included for the following: (1) a method for operating a dispersion nozzle (2) a flotation machine (3) a method for operating a floatation machine.
