| Abstract: | The X-ray photoelectronic spectroscopy data give the grounds for statement that the powerful nanosecond electromagnetic pulse
pretreatment improves sorption activity of pyrite surface and lowers sorption of a collector at arsenopyrite surface. The
research results are verified by test data on the powerful nanosecond electromagnetic pulse effect on the structure and chemical
properties of pyrite and arsenopyrite surface, as well as their electrochemical and flotation properties. |
