成果简介	NOVELTY - Proposed invention relates to methods of investigating interphase phenomena in flotation systems. Invention can be used for numerical determination of interphase parameters to increase efficiency of flotation separation of mineral and technogenic raw materials. Method for potentiometric determination of interphase characteristics in flotation systems consists in the fact that two electrodes made from titanium alloy VT1-0 are placed in a water column, ends of which are installed at different height, at that, the height difference is not less than 5 cm, from below to the column an air supply tube is supplied, which is connected to an air compressor installed above the upper edge of the column, at the bottom of the column a plastic grid is installed with a mesh diameter of sieves of not less than 0.5 cm to ensure dispersion of the supplied air, distilled water is poured, suspension is loaded and air supply is switched on, and for at least 10 minutes, the value of the resulting potential difference is recorded on a voltmeter, wherein potential difference is detected starting from 30 seconds after air supply. Obtained data are sent to a personal computer (PC), on which the values of parameters Ef and C are determined using software packages for numerical and symbolic calculations using the equation: U=Ef ln(t)+C, where U is the recorded values of the arising potential difference, V; t is analysis time, s; Ef is a coefficient characterizing interphase phenomena in a flotation system, V/s; C is a correction factor which takes into account the background caused by the ionic composition of the medium. Then the established values of the parameter Ef for different systems and reagent modes are compared to each other. If the absolute change of the parameter Ef in comparison with the value obtained for the water-air-solid system is large, then the flotation separation will be effective. USE - Measuring. ADVANTAGE - Increased efficiency of flotation separation of ore and technogenic raw materials. 1 cl, 4 tbl, 2 ex
