Journal of the Southern African Institute of Mining and Metallurgy
South Africa is considered as one of the leading countries when it comes to the tailing-related regulations and standards which are aimed at preventing tailings dam failures. Amponsah-Dacosta reported that erosive losses from South Africa’s gold tailings range from 257 to 316 ton/ha/year and cited other works that reported even Review: mine tailings in an African tropical

Since the failures of tailings facilities in South America in particular, an unprecedented Abstract Gold mining in South Africa resulted in vast volumes of tailings, which have been deposited in impoundments. Poor management of most of the tailings dams resulted in the escape of seepage, adversely affecting soils and water quality. Some tailings dams have been partially or completely reclaimed leaving contaminated The environmental impact of gold mine tailings footprints in the

A history of mining in South Africa (ZA)
M M ining in South Africa has been a contentious issue since 15-year-old Erasmus Stephanus Jacobs discovered South Africa’s first diamond, the Eureka, in Hopetown in 1867. It kickstarted what historians call the Mineral Revolution, which made few European opportunists wealthy beyond measure, and saw hundreds of thousands of men leaving Although mining is a cornerstone of the South African economy (), it generates copious amounts of dust. 1 The dusts may be toxic since they may also be contaminated with various toxic metals.For this reason, the prevalence and severity of occupational diseases in the mining industry depends on the ores mined, the Hazards identified and the need for health risk assessment in the South

The Nature and Articulation of Ethical Codes on Tailings MDPI
It is well recognized that the mining industry in South Africa is highly rated for its substantial contribution to the country’s economic growth, including employment and infrastructural development. It is also known that mining and ore processing activities potentially pose a severe threat to public health and environmental well-being, in the way South Africa’s government, mining industry and experts are still in the process of updating the country’s tailings code to align with the global standard, the Minerals Council of South AfricaSouth Africa mine dam collapse highlights patchy regulation

An Assessment of Radiological Hazards from Gold Mine Tailings
In South Africa, the gold mining industry has existed for over a century. As a result, mine tailings are littered everywhere, particularly in the Wonderfonteinspruit Catchment Area (WCA), posing a threat to local communities. The communities living around these areas are threatened by radioactive pollution mainly caused by uranium .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 Environmental exposure to uranium in a population living in close

Tailings Earthworks
The type of tailings dam a mining company builds is directly related to the safety of the structure. Engineers have found that tailings dams tend to be safest, i.e. most resistant to failure and collapse, when they are not built on top of or using previously-deposited tailings.However, the safest dams, like downstream dams, are more September 11, 2022. The Minerals Council South Africa is saddened by the tragedy unfolding at Jagersfontein in the Free State after the collapse of a historic deposition dam and it recommits its members to the highest standards of tailings and waste rock dump management.

In South Africa, a different regulatory regime applies to tailings facilities that are part of a producing or recently closed mine (on-mine tailings facilities) and those that have become separated from recent mining operations (off-mine tailings facilities) as discussed in detail in this article.South Africa acid mine drainage, mainly from gold mine TSFs/tailings dams/slime dams, “remains one of the country’s most serious environmental and socio-economic issues” [ 1(PDF) Environmental Impacts of Gold Mining—With Special

Environmental Impacts of Gold Mining—With Special Reference to South
Gold mining has serious negative environmental impacts, especially due to pollution emanating from tailings storage facilities (TSFs, tailings dams, slimes dams). The most important forms of pollution from TSFs are acid mine drainage (AMD) and high levels of potentially toxic elements (PTEs). AMD arises from the high levels of pyrite in Mining of gold in the Welkom and Virginia areas of the Free State Province in South Africa has produced numerous gold mine tailings, which contain a variety of contaminants.
