uranium mines. Radiation from radon is a continuing concern in the gold mining industry, especially in South Africa. It is a significant concern also for coal miners in China and for underground miners in a number of countries in Africa and elsewhere. One of the world's worst mining disasters from radiation exposure occurred in Canada.
The National Radioactive Waste Management Policy and Strategy lays down options to be considered for managing used fuel and high-level waste. The latter is the main concern among all the different classes of waste. The low volumes of this kind of waste produced by South Africa makes these decisions even more challenging.
The Karoo, a vast semi-desert area that occupies around a third of south Africa's territory, has long been known to harbour substantial sedimentary uranium deposits.. Now the Australian company Peninsula Energy with Russian and other funding is planning to get the radioactive mineral out of the ground on a major scale.. The company has quietly …
A deadly pulmonary tuberculosis epidemic that is blighting South Africa's gold miners is being highlighted this month by biotech company Aeras, which is looking to find a long-term solution to the problem. Aeras's Kari Stoever talks about the stark facts and the economic impact of this largely undiscussed epidemic.
In the management and disposal of radioactive waste, the regulator, waste generator and repository operator have clear responsibilities defined in the radioactive waste management policy and strategy for the republic of south africa. vaalputs is authorised by the national nuclear regulator to be used as a national disposal site for low-level waste (llw) within the nuclear …

Radioactive environmental contamination related to mining is one of global concerns (Černe et al. 2011). The most affected areas will be those in close proximity to the mine tailings due to large concentrations of radioactive material in dust. Research in South Africa has shown that many residential areas near mining
Mining is one of the major causes of elevation of naturally-occurring radionuclide material (NORM) concentrations on the Earth's surface. The aim of this study was to evaluate the human risk associated with …
At the start of February 2022, South African sand mining association ASPASA made an unusual statement, one that challenges the conventional role of an industry membership body. It called for less mining. ASPASA says illegal sand mining is taking a …
their own reasons to include South Africa within the fold. South Africa had the world's largest known uranium reserves buried in gold mine shafts and tail ings piles; in 1950, the United States and the United Kingdom contracted to pur chase some 10,000 tons of South African uranium over the subsequent 14 years.7 At first, the mines themselves ...
Radioactive dumps in communities. Johannesburg and surrounding communities' main concern are mine mountain dumps, made up of crushed, sand-like refuse materials known as tailings produced during the mining process, a complex mixture of metals and dust particles.

The mining and processing of naturally occurring radioactive materials (NORMs) could result in elevated levels of natural radionuclides in the environment. The gold mining in the goldfields of the Witwatersrand Basin of South Africa has resulted in numerous tailing dams that have high concentrations of NORM bearing residue. The aim of this study was to evaluate the …
For 140 years, gold mines in Johannesburg, South Africa have been leaking wastewater contaminated with heavy metals. The acid mine drainage from Johannesburg's estimated 278 abandoned mines and ...
Radioactive dumps could be poisoning hundreds of thousands of people. While Gwede Mantashe is punting nuclear power to solve South Africa's energy crisis, the National Nuclear Regulator (NNR), the ...
disposal. Radioactive material accounts for a very small fraction of the total quantity of dangerous goods transported within South Africa and within the import/export markets. The types of radioactive materials transported in South Africa today, may be broadly divided into two categories. Firstly, there are those materials associated
The Magnetite project in South Africa's Limpopo Province holds immense promise as a valuable source of iron mineralisation, particularly magnetite. MINROM's successful exploration phases have revealed significant potential, laying the foundation for the project's future development. ... MINROM specialises in providing geological services ...
"It unfortunately makes a beautiful sulfuric acid," says Jay Barton, a geochemist and board member of South Africa's Council for Geoscience, that nation's equivalent of the U.S. Geological Survey. The Witwatersrand is not the only region in South Africa where acid mine drainage is a problem, but it is currently the area of greatest concern.
The total capital cost for the processing plant and related facilities is estimated to be approximately 464.5m South African Rand (ZAR). In addition, pre-production capitalised mining expenditure for the open-pit is being estimated at ZAR200m.
The refined platinum produced by the mine during the year was 264,000oz, an 11% decrease from the previous year. The tonnes milled at the Tumela mine also decreased by 7%, to 4.2Mt. The decline in production was the result of safety stoppages and low-grade ore sources. The mining cost of the Tumela mine increased by 14% to R2.9bn ($342m) in 2011.
African Rainbow Minerals (ARM) has agreed to acquire a stake in Bokoni platinum mine (BPM) in South Africa from Bokoni Platinum, for $221m (ZAR3.5bn) in cash.. Bokoni Platinum is jointly owned by Anglo …

Methods. We conducted a cross-sectional study to assess i) uranium (U) concentrations in individual hair samples of children and adults living in close proximity to mine tailings in Northeast- Soweto in Johannesburg, South Africa, and ii) the association between U concentrations in hair and various factors, including zone of residence, socio-demographic and …
The year 2023 proved to be an exceptionally demanding period for the global mining industry, with South Africa facing multifaceted and far-reaching challenges. These challenges have pushed the sector into a state of …
As ore mines ramp up and come on stream, the total number of active surface machines (including trucks, excavators, shovels, loaders, graders and dozers) is forecast to rise from 141,470 in 2020 to 167,367 by 2025.
