Gold mining in South Africa resulted in vast volumes of waste material, mainly in the form of tailings material. Poor management of most of the tailings dams resulted in the release of acid mine drainage that in some cases caused soil degradation and water contamination underneath and around these sites.

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 …

historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the re-processing plant will be re-

DRD Gold, one of the first South African companies to abandon traditional mining to focus on extracting gold from tailings. New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013.

In gold mine tailings, a higher concentration of 583 mg/kg was found by Matshusa et al. in South Africa. Bitala et al. [ 45 ] also reported concentrations as high as 11,200 mg/kg in Tanzania. Nickel exists in gold bearing ore as pyrrhotite (Fe (1−X) S), which can contain up to 5% Ni and pentlandite (FeNi)S 8 .

Driefontein is located in South Africa's West Wits Line goldfield, about 60km south west of Johannesburg. Driefontein Consolidated Ltd (Driefontein) was created in 1981 with the merger of the West Driefontein and East Driefontein mines. In …

" We constructed two TriTanks at our Eldorado mine to retreat tailings. The plant operated for 7 years and was the least problematic of any plant I have ever built and worked. We never dug out a tank. After a power cut, usually not more than 30 minutes, the plant was re-started and within minutes the pulp was back in suspension.

recovering water, mines can also recover metals from tailings. DRDGold was one of the first mines in South Africa to abandon underground mining and focus on tailings mining. The gold tailings reserve has a potential of giving the mine an 82% boost (Solomonds 2018). The tailings currently yield 120 kg or 3,800 oz of gold per month.

The mining industries in South Africa generates huge amounts of mine waste that includes tailings; waste rocks and spoils. The tailings materials are dumped in surface impoundments that turn to be sources of hazards to the environment and the surrounding communities. The main environmental hazards posed by these tailings facilities are associated with their chemical …

The Homestake Mining Company in South Dakota has been successful in using biological oxidation to treat mine and mill effluents (Scott, 1984). In the process, the mine water is blended with the tailings impoundment water that results in a year-round average temperature ranging 50–65 °F that can sustain the biological process.
