Gold-Bearing Minerals: a Link Hub Gold-bearing minerals: a link hub Axel Drefahl • [email protected] Last updated: February 11, 2017 Summary Gold occurs in minerals in association with other elements including silver, copper, lead, antimony, sulfur, selenium and tellurium—to name the most common co-elements. Here, I provide an external link hub: a list of gold-bearing minerals, alphabetically ordered by mineral name, with links to web sites offering mineralogical data and further, detailed information. This document is available at: www.axeleratio.com/minerals/AuMineralsLinks.pdf Copyright c 2017 by author. This work is licensed under the Creative Commons Attribution International Licence (CC BY). http://creativecommons.org/licence/by/4.0/ Keywords. Mineralogy of gold, mineral hub, look-up list. A look-up list with links for gold-bearing minerals Gold-bearing minerals are of economic significance in exploiting gold de- posits. The mode of gold occurrence in ore affects the extractive metallurgy of gold [1, 2]. Since mineralogical factors drive the development of gold assays and metallurgical processes, an organized and reliable access to physical attributes of gold minerals is expedient. The following list of minerals is alphabetically ordered by mineral name. The mineral composition is given by chemical and/or empirical for- mula. The actual percentage of gold deviates from the percentage value derived from ideal stoichiometry, depending on the mineral at hand. The 1 typical gold content in wt% (from Table 2 in [2]) is provided for many minerals at the end of the composition line. The group name characterizes the mineral as gold alloy (inter- metallic alloy or compound) or as compound mineral. In the letter case, the group name is based on the major non-transition-metal constituent(s); for example, sulfotelluride for a minerals rich in sulfur and tellurium. The link list embeds internet links to web pages with data and fur- ther references for the particular mineral. Considered are respective pages of the Handbook of Mineralogy (HdbkMin, http://www. handbookofmineralogy.org/), the MinDat Database (http://www. mindat.org/), the Mineralogy Database (WebMineral, http://www. webmineral.com/) and the online encyclopedia Wikipedia (https:// www.wikipedia.org/).

Modern mineralogy of gold: overview and new data Minéralogie moderne de l’or : bilan et nouvelles données Ernst Spiridonov* and Denka Yanakieva** Abstract: We suppose that it should be useful for archaeologists to have an overview on gold mineralogy, because 1) in ancient times, part of the golden objects were made directly from natural golden nuggets; 2) most of the Au in ores exists as its own minerals. he major part of the Au in the planets and meteorites of our Solar system is found in high temperature solid solutions: metallic Fe-Ni and monosulides Fe-Ni and Fe-Cu. Au leaves them under luid or some other reworking. As a result, Au minerals are formed. hey are mainly developed in hydrothermal deposits of the upper part of Earth’s continental crust.

The millimetric crystals contain inclusions of fluorapatite, titanite, phlogopite, magnetite, ilmenite and iron–copper sulfides. The macrocrystals have a complex gold-rich rim, with four groups of gold alloy: tetra-auricupride (the most abundant gold-bearing phase), Au–Ag (98–54 wt.% Au), Au–Ag–Cu–Pd and Au–Pd–Cu alloys. The inner part of the reaction rim hosts a variety of PGE minerals, such as stannides, antimonides and tellurobismuthides of Pd and Pt. Stannides occur as copper-bearing (taimyrite–tatyanaite series) and copper-free compounds (atokite–rustenburgite series). The main antimony mineral is Sn-bearing mertieite-II. Tellurobismuthides are represented by Te-rich sobolevskite and an intermediate member of the moncheite–insizwaite solid-solution series. The reaction rim also hosts several unknown phases, such as Pd7Bi3, Pd3Bi, Bi2O3•3H2O, and a phosphocarbonate of thorium.

Five varieties of native gold have been identified, based on the set of impurity elements and their quantities, and on intergrown minerals. Native gold in rhyolites from the Ludnaya ore zone is homogeneous and contains only Ag (fineness 720‰, type I). It is in intergrowth with fuchsite or allanite and mertieite-II. In rhyolites from the Slavnaya ore zone, native Citation: Palyanova, G.; Murzin, V.; gold is heterogeneous, has a higher fineness, different sets and contents of elements: Ag, Cu, 840– Borovikov, A.; Karmanov, N.; 860‰ (type II); Ag, Cu, Pd, 830–890‰ (III); Ag, Pd, Cu, Hg, 840–870‰ (IV).

  • Alteration of Gold Nuggets Enriched with Platinum Group
    Alteration of Gold Nuggets Enriched with Platinum Group Elements (PGEs) By: Sophie E. Sperring A thesis submitted in partial fulfilment of the requirements of an Engineering Honours (BE(Hons)) in Chemical and Metallurgical Engineering Degree Murdoch University, Western Australia School of Engineering and Information Technology December 2017 Word Count: 17, 260 1 | P a g e 2 | P a g e Abstract Understanding the mechanisms of incorporation, the form, and the solid-state solubility of Platinum Group Elements (PGEs) in gold nuggets at the nanoscale is critical to future works in gold (Au) nanoscale crystallography. Current works looking at similar samples include Mineral company research into extraction methods of similar samples and research in progress at the University of Western Austral using the alloy of the Au samples for medical purposes. The work completed by this this used Au nugget samples that were taken from Ruby Creek, British Columbia, Canada. The geology specific to the Au samples used is a sub type of the placer alluvial is: Atlin gold placers, which are known for hosting a variety of metals, specific to the Atlin region. Traditional thought for Au nuggets for monocrystalline structures. This steams from research completed by the minerals industry to extract the gold that lent into mineralogical studies. The gold rich rim consists of spherical particles that do not display the silver rich core parallel lamellae texture. The core structure is truncated where it meets the rim of the particle. No PGE particles within the sample area observed. As seen with previous studies the Au samples display a rim that is silver (Ag) enriched.

Approximately seventy primary minerals were known from the district before the present study. All known reliable data on the individual minerals from Jáchymov are presented. New and more complete X-ray powder diffraction data for argentopyrite, sternbergite, and an unusual (Co,Fe)-rammelsbergite are presented. The follow- ing chapters describe some unknown minerals, erroneously quoted minerals and imperfectly identified minerals. The present work increases the number of all identified, described and/or referenced minerals in the Jáchymov ore district to 384.
