Sulfidation of native gold

American Mineralogist, 2014
We use microscopic and electron microprobe techniques to study samples of ores containing native gold with dark rims of Au-Ag sulfides from six deposits and ore occurrences of Russia: Khopto (Au-Cu-skarn), Ulakhan, Yunoe (Au-Ag epithermal), Dorozhnoe, Konechnoe, and Yakutskoe (Au-quartz).

Native Gold of the Chudnoe Gold–Palladium Deposit (Subpolar Urals, Russia)

Russian Geology and Geophysics, 2023
Abstract ––The Chudnoe gold–palladium deposit, located within the Central Ural uplift, is confined to the axial zone of an anticlinal structure complicated by faults. Veinlet mineralization is localized in fractured and brecciated Late Riphean–Vendian rhyolites. Native gold and palladium minerals are concentrated mainly in veinlets of Cr-

Surface Typochemistry of Native Gold

Doklady Earth Sciences, 2018
Using the methods of electron spectroscopy of the surface and SEM–EDS, it is shown that native gold of the deposit related to the epithermal Au–Ag ore formation contains oxidized gold with an oxidation degree of Au (I) or higher on the surface. A thin layer (~15 nm) with high concentrations of Ag and S and an underlying SiO2-bearing layer with a ...

Evolution of Native Gold under Exogenous Conditions

Russian Geology and Geophysics, 2020
Abstract ––A long-term study of the typomorphism of native gold under exogenous conditions gave an insight into its evolution in time and space. The morphology, internal structure, and chemical composition of native gold change depending on the duration of its occurrence under near-surface conditions and on the thermodynamic parameters ...

Evaluation of a diagnostic leaching technique for gold in native gold and gold ± silver tellurides

Minerals Engineering, 2001
Abstract A detailed investigation of the stability in cyanide solutions of native gold and gold ± silver tellurides in a flotation concentrate from the Golden Mile, Kalgoorlie, has been undertaken to assess whether leaching under different conditions can be used to quantify the distribution of Au between native gold and gold ± silver tellurides, as ...

Typomorphism of Native Gold (Geological-Industrial Types of Gold Deposits in the North-East of Russia)

Minerals (Basel, Switzerland), 2022
This study presents the typomorphic features of native gold grains from three different geological-industrial types (GIT) of gold deposits in the North-East of Russia: (1) gold–arsenic-sulfide in black shale strata (Natalka, Degdekan, Karalveem, Maldyak ...

Typomorphic Features and Source of Native Gold from the Sykhoi Log Area Placer Deposits, Bodaibo Gold-Bearing District, Siberia, Russia

Minerals (Basel, Switzerland), 2023
The Bodaibo gold-bearing district in the Lena gold province of Siberia is one of the largest and oldest placer gold-bearing provinces in the world. Approximately 1650 tons of gold has been extracted from the region. Precise studies on the source of these
