Effect of Electromagnetic Pulses on Structural, Physicochemical and Flotation Properties of Eudialyte

The mechanism of change in the surface morphology, physicochemical properties, adsorbability and floatability of eudialyte concentrate as a result of exposure to high-power nanosecond pulses and dielectric barrier discharge in air under the atmospheric pressure is analyzed. The research methods were the Fourier-transform infrared spectroscopy, analytical electron microscopy, atomic force microscopy, confocal laser scanning microscopy, microhardness testing, flow potential determination and other techniques. The rational parameters of energy deposition and reagent regimes toward enhanced efficiency of complex eudialyte-bearing ore flotation are found.
