Abstract

Using X-ray photoelectron spectroscopy, the authors analyze the change in the surface layer composition and chemical state of atoms of chalcopyrite and sphalerite as a result of treatment by high-power nanosecond electromagnetic pulses. General regular patterns and distinctions of modification of the mineral surface and floatability under high-power pulse treatment are found. The research findings are supported by the results of experimental improvement gained in selective separation of sulfides after the high-power nanosecond electromagnetic treatment.
