Gold is a precious commodity and as a result, large scale extraction operations are prevalent. Gold mining has negative results. Soil erosion, the introduction of toxic chemicals into the water supply and the ejection of indigenous people are just a few of the negative results of gold mining.
Rafiei et al., reported a pH value of 7.35 in gold mine tailings in Iran, whereas Mitileni et al., reported pH values of 3.25–6.28 in South Africa and Harish and David pH value of 3.48–8.12 in India. Highly acidic pH has also been observed in acid mine drainage arising from gold mining activity in other studies [25,26].
Gold and diamond mining in South Africa lead to vast immigration to the country, followed by urbanization and great investments. However, the country's mineral council declared 75% of gold mines unprofitable in 2018, predicting a decrease in the industry.

Economic activity in modern-day South Africa has been centred on mining activities, their ancillary services and supplies. The country's stock exchange in Johannesburg was established in 1887, a decade after the first diamonds were discovered on the banks of the Orange River, and almost simultaneously with the gold rush on the world-famous Witwatersrand.
Gold refining. This refers to processes used to processes used to extract and separate the precious metals in mined material, doré, and from recycled products (jewellery and electronics). The main techniques used to remove the final impurities to create high caratage gold are summarised below: REFINING TECHNIQUE. REMOVES BASE METALS.
The South Deep gold mine, located in Gauteng Province of South Africa, is one of the world's biggest gold mines. It is also the seventh deepest mine in the world with a depth of 2,995m below the surface. It has a mine life of 75 years. The underground gold mine also has a large resource base of uranium.
Diamonds were first mined in India, on the island of Borneo in the sixth to tenth centuries, and in 1725 in Brazil. The center of diamond mining has shifted since the 1870's from Asia and South America to Africa: first to South Africa and later to Central, West, and East Africa.
Gold and the economy. Gold mining is a major economic driver for many countries across the world. Well-managed, transparent and accountable resource extraction can be a major contributor to economic growth due to the creation of employment and business opportunities for local people.
For most effective gold mining in South Africa, the method used is hard rock mining, since reserves are typically fully encased in rock deep underground. The invention of industrial air cooling and air quality control systems saw gold mines reach unprecedented depths – the deepest being 3 900 metres.
Anglo Mogalakwena Platinum Mine. This is a big open-pit mine situated in the north-western part of the country, with a reputation of being the largest platinum reserves in South Africa.

In 1975, South Africa was responsible for producing 40% of the gold ever mined. By 2010, however, China affirmed its status as the world's largest gold producer with production of 324 tonnes of gold, followed by Australia (222.8 tonnes), and South Africa with 219.8 tonnes. Today, South Africa produces only 4.2% of the world's gold.

Today the mining towns are of various kinds.
