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 weathering.The descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.

Supergene ores and supergene over of ores (Chapter ...

Supergene ores can be (a) formed in situ from rocks that are being actively weathered in the regolith, or (b) through mineral precipitation from meteoric groundwaters circulating above or at the level of the permanent water table. The term 'supergene ore' is also applied to (c) those parts of originally hypogene ore bodies that have been ...

Ore deposits formed by oxidation and supergene enrichment

Ore Deposits Formed by Oxidation and Supergene Enrichment · When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. · The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. · An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or to ...

Supergene Iron Ore and Disorder - ausimm.com

Supergene processes in banded iron formation (BIF) result in important dissolution, material transport and simultaneous disorder of the residual bands. The rock physical properties such as density, porosity and rheology change during the weathering attack. The itabirite, Paleoproterozoic metamorphic BIF from Quadriltero Ferrfero (QF) - Brazil, shows several weathered facies.

Supergene lateritic iron ores are uncommon when compared with the vast tonnages of BIF-hosted microplaty haematite ores of the world or with the dominant supergene mimetic martite-goethite ores of the Hamersleys. In Australia and to a lesser extent in India and South America, mimetic replacement of gangue minerals by iron hydroxyoxides is a major factor in forming supergene iron ore from ...

Supergene | SpringerLink

Supergene minerals such as sulfides, clays, hydroxides and sulfates are formed in the supergene zone as secondary minerals by the alteration of primary sulfide minerals from the oxidized zone above the water table. Supergene sulfide enrichment is the most common use for the term supergene.

potential ore grade, and requires also that removal of copper be minimal. Distinction between these protore environments is significant in exploration for copper oxide and supergene sulfide enrichment targets because prospects dominated by reactive rock units are likely to display only incipient copper enrichment unless an adjacent or

Supergene processes on ore deposits—a source of heavy ...

The study of supergene processes (i.e., secondary processes running in ore deposits and driven by thermodynamic nonequilibrium between ore-and rock-forming minerals and natural waters, gasses, etc.) is important in order to understand the migration of heavy metals from ore into their adjacent surroundings. The contamination of the local environment can be characterized by the composition of ...
