THE WITWATERSRAND A UNIQUE GOLD MINING COMMUNITY Donald R. Petterson Mr. Petterson is a member of the geography staff at Northwestern University. He was in Johannesburg in 1945 and returned to Africa for four months in the field in 1949. AMONG the great gold fields of the world, the Witwatersrand of South Africa stands out for its uniqueness. Here the discovery of gold has so
Higher gold grades (over 10 gpt) occur concentrated in fluvial channels or "pay streaks", and valleys in the footwall upon which the mineralized conglomerate was deposited. The style of gold mineralization is similar to paleoplacer gold occurrences found in South Africa's famous Witwatersrand gold fields. For updates about our project please subscribe below.
The history of gold in South Africa goes back to 1873 when the first large-scale production began when alluvial deposits were discovered at Pilgrim's Rest, followed shortly by gold discovery in Witwatersrand in 1884. The discovery of gold in the late 19th century gave rise to the development of the city of Johannesburg, Egoli, or the City of

Gold mining Witwatersrand gold occurs in layers of conglomerate rock which form part of the approximately 7000 m thick sequence of sedimentary rocks of the Witwatersrand Supergroup. The layers average about a metre in thickness. The conglomerates are not uniformly gold-bearing and only in certain localised areas is gold present in economically recoverable concentrations. These areas form

Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in northeastern Nevada.
The Witwatersrand Gold Rush was a gold rush in 1886 that led to the establishment of Johannesburg, Though there were smaller mining operations in the region, it wasn't until 1884 and the subsequent 1886 discovery at Langlaagte that the Witwatersrand gold rush got underway in earnest.

Witwatersrand . Location: Central Transvaal (View general location on regional map) Given that the Witwatersrand gold deposits outcrop over a very wide area either side of Johannesburg the goldfield is commonly divided into three districts; namely Central, Eastern and Western.
1886 Australian prospector George Harrison discovers gold on what was then called the Witwatersrand, spurring a gold rush. The tent camp becomes a magnet for fortune hunters who make their way to the mining encampment bringing with them contract labourers. Within three years the place becomes the largest settlement in South Africa.
Witwatersrand gold reefs Mining Method: As I mentioned earlier the gold is predominantly hosted in 20 to 30 cm thick conglomerate units that dip towards the center of the basin at 20 to 42 the reefs obviously cannot be mined to this narrow width and most stopes are just over 1 m in height which means that there are significant dilution of the ore by waste but importantly it means that a high

The Witwatersrand Gold Rush was a gold rush in 1886 that led to the establishment of Johannesburg, South Africa. It was part of the Mineral Revolution. There had always been rumours of a modern-day El Dorado in the folklore of the native tribes that roamed the plains of the South African highveld, and the gold miners that had come from all over the world to seek out their fortunes on the

The Witwatersrand gold mines have to be dewatered constantly to allow mining due to the proximity of the dolomites of the Malmani Subgroup (Morgan and Brink, 1984, Warwick et al., 1987). The dolomites of the younger Transvaal Supergroup overlie the gold-bearing Ventersdorp Supergroup and Witwatersrand Supergroup, with the result that many of the gold mines on the Central and West Rand are
