Observations of Isolated Mobile Au–Br and Au–S Surface Complexes on Au(100) Electrodes
Angewandte Chemie, EarlyView.Fast scanning tunneling microscopy measurements reveal the formation of Au–Br and Au–S surface complexes on Au(100) electrodes in aqueous electrolytes. These complexes are stable and diffuse as molecular entities over the Au surface, demonstrating that surface transport via complexes has to be considered in wet‐chemical growth and dissolution processes.

Singular value decomposition (SVD) for extraction of gravity anomaly associated with gold mineralization in Tongshi gold field, Western Shandong Uplifted Block, Eastern China [PDF]
Nonlinear Processes in Geophysics, 2011 A singular value decomposition (SVD) program on MATLAB platform was effectively used to handle gravity signals for the Tongshi gold field. Firstly, the gravity signals were decomposed into different eigenimages with the help of singular value ...

Implications of Ore Textures for Gold Recovery at Esaase Deposit, Asanko Gold Mine
Ghana Mining Journal, 2022 The Esaase Deposit of the Asanko Gold Mine Ltd (AGM) contains a system of epigenetic gold-related quartz veins hosted by tightly folded and foliated metasedimentary rocks. The gold mineralisation is associated with disseminated sulphide minerals in the quartz-carbonate veins and within the alteration zones of the host metasedimentary rocks. AGM employs

Spatial distribution features and geological settings of the largest gold deposits
Известия высших учебных заведений: Геология и разведка, 2015 The paper considers the problem of distribution and tectonic setting of the largest gold deposits in folded and folded-blocked belts of different types and ages. We present a generalized scheme showing a distribution of 14 giant deposits (with the amount

GOLD IN THE ORE OF THE GOLD-PYRITE DEPOSIT ABYZ (CENTRAL KAZAKHSTAN)
Известия Томского политехнического университета: Инжиниринг георесурсов, 2021 Relevance of the research. More than 20 gold-pyrite deposits are known in the Chingiz-Tarbogatai structural-formational zone. All deposits have one problem in common: during ore dressing, a significant part of the gold goes into the «pyrite» concentrate and is lost along with the «tailings». In increasing gold recovery, we studied in detail the mineral
