Gold Deposits | Goldfo

Witwatersrand Gold Deposits. A special type of gold deposit is the Witwatersrand goldmine in South Africa, which is by far the biggest gold field in the world. About 40,000 tonnes of gold have already been extracted from it. The Witwatersrand goldmine is identified as a so-called mixed type of primary and secondary gold deposits.

Oxidation and Secondary Enrichment of Gold Deposits

In most deposits the movement of the gold is downward, although some exhibit chemical enrichments that indicate a degree of lateral movement of the auriferous solutions. In the oxidized zones of gold deposits both mechanisms have generally operated, and there are rarely sufficient criteria to distinguish which mechanism is dominant.
