Abstract

The effect of high-voltage nanosecond pulses on the phase composition of a galenite surface is investigated by means of XPES and IR Fourier spectroscopy. According to the XPES data, structural-phase transformations caused by pulsed treatment are mainly associated with variations in the chemical state of sulfur atoms, which determines the electrochemical and flotation properties of a semiconductor sulfide mineral: an increase in the electrode potential creates favorable conditions for adsorption of anion collectors and raises the flotation activity of galenite.
