Gold Mining

2021-5-21  Gold grade is a term used in gold mining, and should be used as a measure of the quality of gold ore – that is the raw material obtained from mining. The grade of mined, raw gold ore is measured in grams of gold per tonne of ore. High grade gold ore contains more gold per tonne; this means that more gold is obtained from every tonne mined.

On the source of orogenic gold Geology

Two explanations have been offered for this timing: (1) because orogenic gold deposit formation requires accretionary tectonics, the major periods of formation coincided with periods of continental growth (Goldfarb et al., 2001), and (2) during the Phanerozoic, increased ocean oxygenation facilitated uptake of gold in biogenic and diagenetic pyrite, which became the gold source during later accretion and

The dilemma of the Jiaodong gold deposits: Are they

2014-3-1  There are, however, problems with widespread fluid release from a specific group of Yanshanian granitoids. The exposed granitoids in the Jiaodong region lack any obvious genetic connection with the gold ores. There is a spatial association between the linear belts of gold deposits and the similarly NE- to NNE-oriented Linglong/Luanjiahe granitoids.

On the source of orogenic gold Geology

Gold has historically been a key strategic commodity, and the study of gold deposit formation has long been investigated. Debate on the genesis of so-called “orogenic gold deposits” (>75% of gold recovered through history; Phillips, 2013), continues largely because it is difficult to reliably identify the source of gold.In this issue of Geology, Gaboury.

The gold content of volcanogenic massive sulfide

2010-7-15  Volcanogenic massive sulfide deposits contain variable amounts of gold, both in terms of average grade and total gold content, with some VMS deposits hosting world-class gold mines with more than 100 t Au. Previous studies have identified gold-rich VMS as having an average gold grade, expressed in g/t, exceeding the total abundance of base metals, expressed in wt.%. However,
