Acid leaching of heavy metals from bentonite clay, used in the cleaning of acid mine drainage
(SAIMM, 2010)Heavy metals and sulphates in acid mine drainage (AMD) can be adsorbed onto bentonite clay, leaving clean water and a heavy metal loaded clay precipitate as products. Due to the toxicity of heavy metals, the clay could ... -
Biological reduction of COD and sulphate by SRB in anaerobic moving bed biofilm reactor under high metal loading conditions
(EARET, 2018)The performance of an anaerobic moving bed biofilm reactor (MBBR) containing AnoxKaldnesTM K5 model for the treatment of raw acid mine drainage (AMD) was investigated for the reduction of sulphate and chemical oxygen ... -
Comparative analysis of brewing wastewater and lactate as carbon sources for microbial community treating acid mine drainage in anaerobic MBBR systems
(Taylor & Francis, 2020)This study investigated the effect of carbon sources (n = 2) on the performance of a microbial community in an anaerobic moving-bed biofilm reactor (MBBR) treating acid mine drainage (AMD). The 1.5 L anaerobic MBBR was ... -
The effect of acid mine drainage on the hatching success of branchiopod egg banks from endorheic wetlands in South Africa
(Springer, 2014)Endorheic wetlands are abundant in South Africa, and are more commonly referred to as pans. The pan environment experiences daily and seasonal fluctuations in physico-chemical conditions, caused by variable hydroperiods. ... -
Evaluation of the inorganic water chemistry of the Vaal River
(2015)One of the most essential resources for life on our planet is water. A concern for water resource sustainability has shifted towards the sustainable development of clean water body resource (SWDF, 2009). Data for the Vaal ... -
Generic source term determination for tailings storage facilities in the East Rand Basin
(North-West University, Potchefstroom Campus, 2018)The prolonged leaching of gold tailings is a continuous concern in the East Rand Basin typically resulting in acid generation and the release of elements. The leachable constituents from the tailings influences the water ... -
Geo-environmental and physical risk associated with the derelict and ownerless gold mines from Transvaal- Drakensberg and Barberton Greenstone Belt Gold Fields, Mpumalanga Province, South Africa
(North-West University, 2019)Historically mines had poor reputation for addressing environmental and safety concerns during mining and at mine closure as a result historic mining areas are left with large open pits, unsealed shafts filled with water ... -
A holistic view on the impact of gold and uranium mining on the Wonderfonteinspruit
(North-West University, 2012)The Wonderfonteinspruit (WFS) flows through the richest gold mining region in the world and has subsequently been exposed to the related pollution for more than a century. In order to determine the extent of mining related ... -
Influence of mining pollution on metal bioaccumulation and biomarker responses in cave dwelling fish, Clarias gariepinus
(Springer, 2016)Cave ecosystems remain largely unstudied and risk being severely degraded as a result of anthropogenic activities. The Wonderfontein Cave, situated in the extensive gold mining region of the Witwatersrand Basin, is one ... -
Mobility potential of metals in acid mine drainage occurring in the Highveld area of Mpumalanga Province in South Africa: implication of sediments and efflorescent crusts
(Elsevier, 2017)Prediction of the dispersion of pollutants from the acid mine drainage is an important step toward the development of remediation strategy and mitigation of environmental impact. Geochemical studies are often carried out ...
