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. ... -
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 ... -
Unlocking water potential in drylands: Quicklime and fly ash enhance soil microbiome structure, ecological networks and function in acid mine drainage water-irrigated agriculture
(Heliyon, 2024)In water-stressed regions, treated acid mine drainage (AMD) water for irrigated agriculture is a potential solution to address freshwater scarcity. However, a significant knowledge gap exists on the short and long-term ...
