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 ...

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-

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 ...

The host minerals of native gold

Economic Geology, 1944
An intensive review of the literature as well as microscopic study of many ores shows that gold occurs most frequently in direct contact with the following ore minerals in the order named: pyrite, arsenopyrite, galena, sphalerite, chalcopyrite, bismuth minerals, pyrrhotite, tetrahedrite-tennantite.

Trace element distribution in native gold

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1996
Abstract PIXE with the HIAF proton microprobe has been used to study the trace element distribution in gold from alluvial sources and ore samples, to investigate the possibility of identifying characteristics distributions associated with different types of geological environments.

A review of the flotation of native gold and electrum

Minerals Engineering, 2001
Abstract Native gold and electrum are naturally-occurring alloys containing gold and silver and a little copper. They are the most common and important forms of gold in ores. Their recovery by gravity concentration, cyanidation, or flotation from ores, typically containing 0.1–20 g/t Au is of great commercial importance.

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 ...

Museum specimens of native Scottish gold

Transactions of the Edinburgh Geological Society, 1879
There are several reasons that lead me to suppose that it is desirable to place upon record some account of the various samples of Scotch gold and gold quartz, which are to be found in our national and other public museums. The most important of these reasons is, that I believe not a few of the specimens in question to be spurious, in so far as they ...

Native gold in a Hawaiian alkalic magma

Economic Geology, 2003
Native gold found in fresh basanite glass from the early submarine phase of Kilauea volcano, Hawaii, may be the first documented case of the transport of gold as a distinct precious metal phase in a mantle-derived magma. The gold-bearing glass is a grain in bedded volcanic glass sandstone (Japan Marine Science and Technology Center (JAMSTEC) sample ...
