Yuningsih et al.) for Cibaliung deposit.
characteristics of refractory gold ores that occur in the hypogene environment of epithermal and mesothermal gold-silver telluride deposits. Metallurgical problems associated with gold-bearing tellurides and "invisible gold" (i.e., structurally bound gold and inclusions of native gold <1,000 Å in size) are addressed. The use of secondary ion
The inferred reserve is approximately 2 million tons at 5.7 g t−1 gold and 41.5 g t−1 silver at a cut‐off of 4 g t−1 Au, which equates to approximately 12.5t of Au and 91.4t of Ag.
The Tuvatu gold-silver telluride deposit with reserves of 13 t Au is the second largest gold deposit in Fiji after the large Emperor gold telluride deposit (production, and proven and probable reserves of 280 t Au). The deposits are 50 km apart and occur along the >250-km east-northeast–trending Viti Levu lineament. They are …

Gold-(silver)-telluride ores are important class of epithermal deposits (e.g. Sacaramb mine in Romania, Alderton and Fallick, 2000; Emperor mine, Vatukoula, Fiji, Pals and Spry, 2003; Golden Mile, Kalgoorlie, Western Australia, Shackleton et al., 2003). Such deposits are characterized by large tenor of Au and high concentrations of Te (Smith et ...
In copper ores, tellurium forms stable crystalline compounds (called tellurides) of gold, silver, bismuth, mercury, platinum and palladium that tend to accumulate in residual ore fluids. The element was first identified in 1782 in Transylvanian gold ore. For more than a century, tellurium was considered an experimental material having little ...
The Golden Sunlight gold-silver telluride deposit, hosted primarily within the Mineral Hill breccia pipe, is spatially related to a high-level, Late Cretaceous multiphase, alkaline to subalkaline porphyry system (latite porphyries, quartz monzodiorite, and lamprophyres). Base metal veins and manganese (rhodochrosite) mineralization occur …

Gold-(silver)-telluride (selenide) ores occur as epithermal orogenic and intrusion related deposits. Although Te and Se are chalcophile elements and share geochemical affinity with Au, formation of selenides and other elements Ag-Au require acidic or reducing environments. The thermodynamic stability conditions for Au and …
The Mysterious Telluride Minerals. August 2020 by Chris Ralph …let's dive in and take a closer look at these rich gold and silver-bearing minerals to find out what they are, where they form, and how to identify them. ... Most gold-bearing veins in this region are controlled by fractures associated with the Melones Fault, a late Cretaceous ...
Gold-(silver)-telluride (selenide) ores occur as epithermal orogenic and intrusion related deposits. Although Te and Se are chalcophile elements and share geochemical afinity with Au, formation of selenides and other elements Ag-Au require acidic or reducing environments.

Gold– (silver) tellurides are important accessory minerals, carrying a significant proportion of the gold endowment in some low to medium temperature …
Silver telluride and gold telluride showcase favorable thermoelectric properties, such as a high Seebeck co-efficient, low electrical resistivity and low thermal conductivity. Notably, silver telluride has demonstrated excellent thermoelectric properties [8,9], while gold telluride has shown potential in thermoelectric applications [6].
studies of gold in gold-silver telluride deposits show that it occurs as "visible gold" extracted by cyanidation, and as visible gold and "invisible gold" that are unamenable to …
Textural, Fluid Inclusion, and Stable Oxygen Isotope Constraints on Vein Formation and Gold Precipitation at the 007 Deposit, Rice Lake Greenstone Belt, Bissett, Manitoba, Canada. The 007 gold deposit is located within the 2.99–2.70 Ga Rice Lake greenstone belt, Manitoba, Canada.
The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].

The low-sulphidation epithermal gold-telluride deposit of Emperor, Fiji (11.5 Moz) is hosted by Late Miocene-Early Pliocene shoshonitic rocks and is one of the best studied examples (e.g., Pals
The Tuvatu gold–telluride prospect is one of several epithermal gold systems along the >250 km northeast trending Viti Levu lineament, Fiji, which are genetically associated with alkalic magmatism. Vein structures contain a variety of sulfides, native elements, sulfosalts, and tellurides. Calaverite is intimately associated with various …
The Sandaowanzi gold telluride deposit is a new discovery with dominance in gold tellurides in Northeastern China. The deposit is hosted in quartz veins intruding sub-alkaline volcanic rocks. There are two types of gold telluride ores in the Sandaowanzi ore deposit, i.e. the vein ores and the disseminated ores.
