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.

Keywords: Kazakhstan, Northern Ulytau, copper-pyrite ores, mineral phases of rhenium, lead, copper, molybdenum and bismuth
