The actual gold deposits themselves are quite thin and the surrounding rock matrix is very hard. Techniques such as cyanidization, or the removal and concentration of gold with cyanide was developed in response to the difficulties …

The new results confirm that the Witwatersrand gold deposits are "placer" deposits -- that millions of years ago, ancient rivers carried gold particles, along with sand and silt, into …

Almost every imaginable genetic model has been proposed to explain the Witwatersrand gold deposits, ranging from syn-sedimentary placer to epigenetic magmatic or metamorphic origins.

The gold fields of the Witwatersrand Basin in South Africa are, by a landslide, the largest single gold producing district in the world. It has produced some 2 billion ounces over a century of mining and at an average grade of 15 g/t Au with a current head grade of 6-10 g/t Au and they still have estimated reserves of some …

Aspects of the genesis of many gold deposits remain unanswered, highlighted by the continued debate into the origins of the gold deposits of the Witwatersrand basin.

Archean orogenic gold deposits are widespread in the Dharwar Craton and account for almost 80% of cumulative Indian gold production. The Dharwar Craton hosts significant Gold prospects and the Hutti Gold deposit …

Other important deposit types include Carlin, Au-rich VMS and Witwatersrand deposits. The key geology features of the ore-forming environments and the key geologic manifestations of the …

Accretionary or peripheral orogens contain gold deposits in the Archean of Australia, Canada, Africa, India, and Brazil and the Mesozoic and Cenozoic gold fields of western North America, i.e., the famous Mother Lode belt.

The Witwatersrand Basin in South Africa holds the world's largest gold deposits across a 200-km long swathe. Individual ore deposits are spread out in thin layers over areas up to 10 by 10 km and contain more gold than any other gold deposit in the world.

By comparison, gold grades from South Africa's prolific Witwatersrand Basin averaged around 9g/t over a similar time frame. 2. In subsequent years, gold was primarily extracted from three mines within the East Kolar region: Champion, Mysore and Nundydoorg.

Archean orogenic gold deposits are widespread in the Dharwar Craton and account for almost 80% of cumulative Indian gold production. The Dharwar Craton hosts significant Gold prospects and the Hutti Gold deposit stand as the only Gold producing Mine.

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.

Almost every imaginable genetic model has been proposed to explain the Witwatersrand gold deposits, ranging from syn-sedimentary placer to epigenetic magmatic or metamorphic origins.

Other important deposit types include Carlin, Au-rich VMS and Witwatersrand deposits. The key geology features of the ore-forming environments and the key geologic manifestations of the different deposit types form the footprints of ore systems that …
