In 1970, South Africa produced 995 tonnes or 32 million ounces of gold, two-thirds of the world's production of 47.5 million ounces. [2] Production figures are for primary mine production. In the US, for example, for the year 2011, secondary sources (new and old scrap) exceeded primary production. [3]

Gold mining can significantly alter the natural environment. Gold mining activities in tropical forests are increasingly causing deforestation along rivers and in remote areas rich in biodiversity. [73] [74] Mining has increased rainforest loss up to 70 km beyond lease boundaries, causing nearly 11,670 km 2 of deforestation between 2005 to 2015 ...

Orogenic gold deposits are responsible for approximately 75% of the world's gold production at over 1 billion ounces, when accounting that the origin of many gold placer deposits were orogenic in nature. [25] [46] The price of gold at a given time will have an impact on whether a deposit will be economically feasible.
The world's 5th largest gold producer (170 tons in 2012) that is home to two of the world's ten largest gold mines. [79] As recently as 2007 South Africa was the world's top gold producer. The drop in its global ranking is not due to resource depletion (South Africa ranks close behind leader Australia in reserves) but rather to its high costs ...
The Carlin–type deposits represent some of the largest hydrothermal gold deposits in the world. [7] The invisible nature of the gold in the deposit makes it difficult to find deposits of that kind. The class of deposit was defined after the Carlin mine became a mass producer of gold in the 1960s and it was recognized that other deposits of ...
