Investigations in the Field of Flotation with a Steam-Air Mixture

摘要

The influence of the induction and relaxation time of the deformed adsorption layer of the bubble on the stability of the wetting film is investigated theoretically and experimentally. It is shown that, during flotation by a mixture of dry air with the saturated water vapor (aerosol), the adherence selectivity increases due to stabilization of the wetting film. A method for computing the vapor flow rate during flotation with aerosol that does not require empirical information is developed.
