    2020-12-30 · The Witwatersrand gold deposit is the largest in the world. Thermodynamic calculations show that such rich accumulations of gold could be linked to abundant volcanism, primitive life and the oxygen-free atmosphere of the Archaean. The Witwatersrand Basin in South Africa is one of the best-preserved records of fluvial sedimentation on an Archaean continent1.Witwatersrand Gold Deposits Mineral Processing & ,2021-1-8 · Here is some history of the Witwatersrand Gold Style Ore Deposits as they related to South Africa since the arrival of the Dutch and the southernmost tip of the continent in 1652.

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.
