Extremely acidic eukaryotic (Micro) organisms: Life in acid mine drainage polluted environments—mini-review
Acid Mine Drainage (AMD) results from sulfide oxidation, which incorporates hydrogen ions, sulfate, and metals/metalloids into the aquatic environment, allowing fixation, bioaccumulation and biomagnification of pollutants ...
Membrane technology applied to acid mine drainage from copper mining
The objective of this study is to evaluate the treatment of high-strength acid mine drainage (AMD) from copper mining by nanofiltration (NF) and reverse osmosis (RO) at pilot scale. The performances of two commercial ...
Influence of extremophiles on the generation of acid mine drainage at the abandoned pan de azúcar mine (Argentina)
(MDPI AG, 2021-01-29)
The risk of generation of acid drainages in the tailings of the Pan de Azúcar mine that closed its activities more than three decades ago, was evaluated through biooxidation studies using iron-and sulfur-oxidizing extremophilic ...
Treatment of Chilean acidic mine drainages using sorption process based on magnetic metal oxides and modified nano-structured silicates
The general goal of this research is to study the application of novel sorption methods to eliminate the inorganic contaminants existent in samples of Chilean acidic mine drainages. Acidic mine drainages (AMD) are generated ...
Influence of carbon source and inoculum type on anaerobic biomass adhesion on polyurethane foam in reactors fed with acid mine drainage
(ELSEVIER SCI LTD, 2011)
This paper analyzes the influence of carbon source and inoculum origin on the dynamics of biomass adhesion to an inert support in anaerobic reactors fed with acid mine drainage. Formic acid, lactic acid and ethanol were ...
Rare Moss-Built Microterraces in a High-Altitude, Acid Mine Drainage-Polluted Stream (Cordillera Negra, Peru)
The Rio Santiago in the Cordillera Negra of Peru is severely contaminated by acid mine drainage in its headwaters. In a strongly acid stream, at about 3800 m above sea level (masl), microterraces were found with terrace ...
Diversity of bacterial communities in acid mine drainage from the Shen-bu copper mine, Gansu province, China
(Pontificia Universidad Católica de Valparaíso, 2008)
Addition of organic acids to acid mine drainage polluted wetland sediment leads to microbial community structure and functional changes and improved water quality
Acid mine drainage (AMD) is a serious environmental problem worldwide that requires efficient and sustainable remediation technologies including the use of biological mechanisms. A key challenge for AMD bioremediation is ...
Novel adsorbents based on calcium silicates modified with Fe and Al to remove As and sulphate from acid mining drainages
One of the main environmental worries in mining is how to deal with the formation of so-called "acid mine drainage" (AMD), which consist of naturally occurring water, associated with chemical and biological oxidation of ...
An Overview of an Acidic Uranium Mine Pit Lake (Caldas, Brazil): Composition of the Zooplankton Community and Limnochemical Aspects
Water samples were collected quarterly for 1 year from the newly created Osamu Utsumi uranium mine pit lake, Brazil, which is affected by acid mine drainage (AMD). The water presented mean pH values of 3.8, high mean ...
