Abstract The article describes the studies on the material constitution of two lead–zinc ore samples from the Gorevka deposit. The samples are difficult ore because of fine dissemination of galena and its complex intergrowth with sphalerite; feature partial replacement of lead sulfide by anglesite and cerussite; contain colloform galena. The initial ore samples …
