First data on Re-containing minerals in the copper-nickel ores of the Pay-Khoy highland (Nenets autonomous okrug)

The results of structural-morphological, microprobe and spectroscopic studies of high rhenium molybdenite (up to 2.5 wt.% Re) and unidentified rheniumcontaining phases (up to 26 wt.% Re) of the composition Re-Fe-Pb-(± Bi, Sb)-S from coppernickel ores of the occurrence Pervyi on the Pay-Khoy, are considered. It is established that rhenium within molybdenite is distributed unevenly: from 0.n to 2.54 wt. %. Using the Raman scattering method for molybdenite, the following bands (λ = 632.8 nm): 178-180, 188-189, 227-228, 346-347, 380-383, 406-409, 418-419, 455-459, 466, 529-530, 559-560, 570, 592, 600, 631,643-644 cm-1 were obtained.
