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 gold-bearing rocks--even rocks containing only traces of gold--are subjected to 2. The second circumstance involves mineral deposits containing

Multi-stage enrichment processes for large gold-bearing

Jul 01, 2016 Abstract A review of previous studies of the world's large hydrothermal gold deposits indicates that the largest deposits tend to show complicated parageneses where multiple gold enrichment events and processes have been involved in the deposit generation.

Oxidation and Secondary Enrichment of Gold Deposits

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.

Here Is The Correct Way To Effectively Recognize Gold Ore

Dec 07, 2018 Gold is a precious metal and also a chemical element with atomic number 79. When not mixed with other metals it is reddish yellow, heavy, soft, easy to work with, and conducts electricity readily. Gold is part of a group of metals called noble metals, which include gold, silver, and platinum; they all resist chemical action, do not corrode, and are not easily changed by acids.

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

Gold enrichment in hydrothermal sulfides from the Okinawa

Jan 01, 2020 Such gold enrichment in low-temperature Si–Ba-rich ores resembles gold deposition in the uppermost chert–barite-rich cap in ancient VMS hydrothermal systems on land (Huston and Large, 1989, Large, 1990). Hence, low-temperature Si–Ba–Fe-rich hydrothermal sulfides may also be considered an important contributor to gold enrichment in
