ABSTRACT

Using the methods of X-ray and Mössbauer spectroscopy, scanning electron microscopy, there were studied the samples of Norilsk ore types in order to identify compounds containing Сu, Ni, Co. The presence of native elements and intermetallic show a reducing mode of ore formation processes. The magnetic phase has the spectrum composed of two six-linear spectrums. The peaks on the spectrum borders show the oxide presence. Most of the bulk of Cu, Ni is not dissipated in the crystal lattices of the ore, but it is part of the ore sulphides. The presence of the characteristic structures of the solid solutions decomposition shows a wide temperature range of sulphide crystallization.

Keywords:ores of the Norilsk type, X-ray, Mössbauer spectroscopy, scanning electron microscopy.
