Processing technologies for gold-telluride ores

The six major gold-bearing tellurides are calaverite (AuTe2), sylvanite [ (Au, Ag)2Te4], montbrayite [ (AuSb)2Te3], krennerite [ (Au1-x, Agx)Te2], petzite (Ag3AuTe2) and muthmannite (AuAgTe2)....

Treatment of Gold–Telluride Ores - ScienceDirect

2016-1-1  Physical Properties of Calaverite When heated in air to around 500 °C, the gold tellurium bond is readily broken, producing tellurium dioxide and gold metal. Above 800 °C, the TeO2sublimes off. The mineral itself is remarkably gold rich, with the gold being found in a molecular association with the element tellurium.

Processing technologies for gold-telluride ores

2016-9-12  Ellis provided a very detailed plant cyanide leaching process for gold telluride minerals. About 23% of the gold in a KCGM concentrate was gold tellurides, mainly calaver-ite (AuTe2) with small amounts of petzite (Ag3AuTe2). Ellis introduced an extra oxidative step using hy-pochlorite leaching immediately after leaching with 0.1wt% NaCN at a pH value of 9.2 for 24 h. Lime was used to adjust pH, and the leaching conditions were changed to a lower cyanide concentration. According to the report, several re-peated oxidation steps were needed for particle sizes larger than 10 µm. Pleysier et al. also examined the leaching process of gold telluride ores from a KCGM flotation con-centrate sample. The leaching process
