Abstract
A dispersion nozzle for dispersing a liquid with a gas, has a gas feed nozzle and a tubular mixing arrangement which has an inlet zone for the gas and the liquid and an outlet zone for a gas/liquid mixture. The mixing arrangement adjoins the gas feed nozzle. The gas feed nozzle is tapered in the direction of the mixing arrangement and opens into the inlet zone. The mixing arrangement has at least one liquid intake opening in the inlet zone. In the inlet zone a ratio of a diameter DG of a gas outlet opening of the gas feed nozzle and an internal diameter DM of the mixing arrangement is in the range from 1:3 to 1:5. A gas regulating valve meters a quantity of the gas being supplied with the gas feed nozzle. The dispersion nozzle may be used in a flotation machine.
