Mineralogical features of ore of copper-pyritic deposit Yubileinoye (S. Urals)

Abstract

Mineralogical composition features of large copper-pyritic Yubileinoye deposit (slightly metamorphized and now exploited by open pit) are studied. Major ore structures include impregnated, spotted, banded, stringer structures. Two generations of chalcopyrite, sphalerite and quartz, and 3 generation of pyrite were found. Proper gold minerals occur as tiny isolations of native gold (fineness 631-662) in veinlets accompanied by tennantite-tetrahedrite and galena; the connection of native gold with these minerals is supported by close correlation Au with Pb, As and Sb in ore composition.
