▪ Levin, V.L., Stepanets, V.G., Li, E.S., Bekenova, G.K., Khakimzhanov, M.S. (2020): Discovery of rhenium sulfides in copper sulfide ores from the Mayke ore occurence (Ulytau, Central Kazakhstan). Zapiski RMO (Proceedings of the Russian Mineralogical Society), 149(5), 82-98.

Abstract:
During mineralogical studying of copper–pyrite ores from the Mayke ore occurence of Northern Ulytau, microinclusions of sulfides with rhenium, molybdenum, copper, lead, and bismuth in different proportions were found. Microinclusions differ in shape and chemical composition. Determined by microprobe the chemical compositions of the 8 sulfides include rhenium (up to 49.46 wt %), iron, copper, molybdenum, lead, and bismuth. Calculated crystal chemical formulas the sulfides: (Re,Mo,Cu ± Fe,Os,Pt)2S3, (Re,Mo)S2, ReS3, Re2S7, (Pb,Re,Zn)S2, (Pb,Re,Fe)S2, (Pb,Re,Fe)2S3, (Re,Fe)(Pb,Bi)S3. First discovered: the Pb-Re-Zn-S phase; Rh and Sb were found together in the Re–Fe–Pb–Bi–S mineral phase; first identified ReS3 and Re2S7 rhenium sulfides.
