  • Ore deposits formed by oxidation and supergene enrichment

    Secondary enrichment can affect most classes of ore deposit, but it is notably important in three circumstances: 1 The first circumstance arises when goldbearing rockseven rocks containing only traces of goldare subjected to lateritic weathering Under such circumstances, the gold can be secondarily enriched into nuggets near the base of the laterite The importance of secondary

  • 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 component Such enrichments require no chemical

  • Supergene (geology) Wikipedia

    In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weatheringThe descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements

    Such gold enrichment in lowtemperature Si–Barich ores resembles gold deposition in the uppermost chert–bariterich cap in ancient VMS hydrothermal systems on land (Huston and Large, 1989, Large, 1990) Hence, lowtemperature Si–Ba–Ferich hydrothermal sulfides may also be considered an important contributor to gold enrichment in

    Within gold ores, the element occurs in nature chiefly as native gold, which is by far the most common gold bearing mineral In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent Therefore whenever gold is found encased in pyrite
