Co and Тi minerals in ores of the Mikheevskoe porphyry Cu deposit (South Urals)

Year: 2025

Type: article

Abstract: Co and Ni minerals are described in ores of the Mikheevskoe porphyry copper deposit (South Urals, Russia). Minerals of the cobaltite–gersdorfte series (CoAsS–NiAsS), violarite (FeNi2S4), millerite (NiS), pentlandite (Ni5.5Fe3.4)8.9S8.0 and melonite (NiTe2) are identifed. They overgrow pyrite, chalcopyrite and bornite and belong to late low-temperature assemblages. Cobalt and Ni are also incorporated in pyrite. The latter, being the most widespread mineral of the deposit, is a major carrier of these metals. The variability of Co and Ni minerals is determined by the presence of serpentinites, which replaced ultramafc rocks.
