摘要: The effect of powerful nanosecond electromagnetic impulses (PEMI) on the surface and flotation properties arsenopyrite carbonate gold-bearing pyrite from Darasunsk deposit has been studied. X-ray-phase diffractometry, X-ray photoelectronic IR Fourier-spectroscopy, raster electronic microscopy were employed in investigations. It was established that alteration phase composition depends non-linearly terms treatment (dry or wet) number used appreciable influence oxidation hydrophobicity minerals, thus allowing selective separation by neutral medium.
