摘要：

The mechanochemical processing of the copper sulphide with iron in a high-energy mill was studied. The nanosized copper of 10 nm crystallite size and the hexagonal pyrrhotite 1C were identified among products of the reaction by methods of XRD and Mossbauer spectroscopy. In the surface layer of products after the mechanochemical processing copper in its mono- and bivalent forms was identified by XPS method.
