Many diverse ore systems are classified together as iron oxide copper-gold (lOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of ore-forming fluid, metals, or other ore components. Such deposits have (1) Cu, with or without Au, as economic …

Carlin-type deposits represent a major source of gold, and account for ~8% of the current global gold production (Muntean and Cline, 2018).Following the definition of the Carlin-type deposits in Nevada, similar ore deposits (Carlin-like) were reported in the Youjiang basin of SW China (e.g., Peters et al., 2007; Su et al., 2009a, 2018; Hu and …
Comments on "Mineral chemistry of hydrothermal alteration assemblage in hanging wall Shahapur Granite associated with vein type Gogi uranium deposit, Bhima basin, Eastern Dharwar Craton, India: Implication for physico-chemical conditions of ore formation" by Mohd Qaim Raza and Nurul Absar. [Ore Geol. Review, 2021, 128, 1–20] D.K. Sinha.
The application of deposit-scale structural targeting to orogenic gold deposits is primarily concerned with locating volumes of higher-grade mineralisation (ore shoots) within a broader, host structural system. Although empirical correlations between structural heterogeneities and ore shoots have long been noted and certain key physical …
However, it is still unclear which features of these ore-bearing intrusions are crucial for the enormous metal enrichment and how they correlate with magmatic fertility. In this study, we address these questions by comparing the petrological and in situ major and trace element geochemistry of apatite for the ore-bearing and ore-barren intrusions.
The unequivocal crosscutting relationship, contrasting mineral assemblages, and physiochemical conditions suggest that the W and Au mineralization at Zhaishang are due to two separate mineralization events. ... if any, of country rock compositions on the formation of gold ore systems in the Jiaodong Peninsula. Scheelite from the two gold ...
The gold recovery of the ore was improved from 57% to 80% during CIL, after the ore was treated with 4.48 mM naphthalene sulfonate at pH 11.3 adjusted by 4.36 mM Ca(OH) 2. The main factor, that was likely responsible for the improved gold recovery, was the passivation of the adsorption sites on the carbonaceous matter in the ore.
Arsenious and sulphur-bearing micro-disseminated gold ore is a kind of typical refractory Carlin-Type. The gold in Carlin-Type gold ore grains is distributed finely, existing as invisible or submicroscopic gold, encapsulated in arsenopyrite and pyrite. The technical difficulty of treatment Carlin-Type gold ore lies in how to release the fine gold …
In this study, we assess the hypothesis that the contrasting behavior of Au and of Pt in surface environments is driven on the most fundamental level by differences in the biological toxicity of mobilized Au versus Pt. ... The Jiaodong gold (Au) province is the largest gold ore cluster in China and is an important world-class Au cluster area ...
2.2. Preg-robbing test. The ability of the gold concentrate to adsorb Au(CN) 2 − was determined for each flotation concentrate. 1 g of each concentrate was suspended in 5 mL of a solution containing 0.26 mM Au at pH 11 for 24 h at room temperature and 150 rpm speed. The residual gold in the solution was determined by ICP-OES (Perkin Elmer …
The Dongping gold deposit, located near the northern margin of the North China Craton, contains ore bodies spatially associated with the Devonian Shuiquangou syenite, Cretaceous Shangshuiquan granite, and Archean metamorphic rocks. Major and trace elements and S–Pb isotopes of pyrite from two stages of gold-quartz veins and wall …
The Jiaodong gold province is one of the most important gold fields globally and the largest in China. The Denggezhuang gold deposit is situated in the eastern portion of the Muping metallogenic belt, within the Jiaodong gold province. Despite many recent investigations, detailed mineralogical studies, particularly on auriferous minerals such as …
open access. Highlights: •. Invisible gold occurs dominantly as solid solutions (Au +) in the lattice of pyrite and pyrrhotite. •. The ore-forming fluid is dominantly …
The crustal metamorphic and remobilization model is thought to be the dominant ore-forming process for orogenic gold deposits that are metamorphosed to upper greenschist facies (Pitcairn et al ...
Gold ores are classified "free-milling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as …
However, more integrated studies that combine structural geology, ore petrology, particularly, the textures of gold and gold-related sulfides, and robust geochronology demonstrate that gold ...
Gold-rich porphyry Cu deposits, an essent ial source of gold and copper in the world, are usually associated with calc-alkaline magma, accompanied by multiphase intermediate – felsic intrusions ...

Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations were low …
Carlin-type gold deposits are among the most important gold-bearing hydrothermal ore systems and are mainly located in Nevada, USA, and southwestern China. However, the source and evolution of the ore-forming fluids for these deposits remain controversial, especially those found within China. In this study, lithium and …
