Enrichment of Gold Above Background | SpringerLink
17/06/2022· Enrichment of an element above its average abundance in the Earth’s crust is required to form any ore deposit For gold, that enrichment is around 10,000 times which is more than virtually any other element, and the high enrichment implies special partitioning in Nature Enrichment follows provinciality as the second of five characteristicsThe Source of Gold May 08, 2007 0183 32 The fourth class of gold ores comprises the goldtelluride group The gold telluride ores occur with silver, or with silver, lead and antimony, or as native gold accompanied by other tellurid These ores are often sent direct to the smelters for treatment A fifth type is the disseminated ore type They are often low in grade but largeenrichment of gold ore operaparciparlach

Oxidation and Secondary Enrichment of Gold Deposits
The supergene enrichment of gold in deposits may take place by a simple mechanical process, by chemical means, or by a combination of these First, the enrichment may be primarily the result of the chemical removal of a large part of the gangue minerals, in which case the gold migrates slowly downward by gravity or is left behind as a residual componentGold enrichment in the main oreforming stage of the northwest Jiaodong gold deposit probably was realized by multiple phases of fluid pressure fluctuation, which subsequently led to repeatedly dissolution and reprecipitation of Au from pyrites due to decreasing oxygen fugacity and increasing pH values of the oreforming fluids Graphical abstract Download : Download highDecompression induced enrichment and precipitation of gold in
