Coal acid mine drainage treatment using cement kiln dust
(Universidad Nacional de Colombia Sede Medellín, 2014-08-25)
Sulphurs are present in different rocks. During mining activities and the sulphur removal processes Acid Mine Drainage (AMD) may be produced, by sulphate ions (SO4 2-) in solution. AMDs are the main source of pollution ...
Hydrogeological Analysis of Sulfide Tailings at a Uranium Mine Using Geophysical and Hydrochemical MethodsAnálisis hidrogeológico de relaves de sulfuro en una mina de uranio mediante métodos geofísicos e hidroquímicos
(2021-09-01)
A hydrogeological analysis was conducted of aquifer systems within a sulfide-rich tailings pile and underlying rocks at a uranium mine to understand the generation and transport of AMD. A geophysical investigation was ...
Technology intervention to change the perception of acid mine drainage as energy

Comparative study of alternative methods for the simultaneous determination of fe+3 and fe+2 in leaching solutions and in acid mine drainages
(PERGAMON-ELSEVIER SCIENCE LTD, 2005)
In leaching solutions coming from the hydrometallurgical processing of copper sulphides, it is necessary to determine the concentrations of Fe-total,Fe- Fe+2 and Fe+3. It is known that the 5-sulfosalicylic acid (SSA) forms ...

Treatment of acidic mine drainage in an adsorption process using calcium silicate modified with fe(iii)
(2017)
Two compounds based on calcium silicate hydrate and modified with Fe(III), using FeCl3 and Fe(OH)(3) as iron sources, were synthesized, characterized and evaluated as adsorbents for removing ionic species from an arsenic ...
Environmental Impact on Soil, Water and Plants from the Abandoned Pan de Azúcar Mine
(Trans Tech Publications, 2013-10)
an de Azúcar abandoned mine is located in Jujuy province, Argentina. The impact of that pollution was evaluated determining the density and the composition of the vegetation around the tailings. Also soil and plants samples ...
Evaluación de la cinética de adsorción de Fe (III) de drenaje ácido de mina mediante organoarcillaEvaluation of the adsorption kinetics of Fe (III) of acid mine drainage by organoclay
(Universidad Nacional del Centro del Peru, 2022)
Genomic signatures and co-occurrence patterns of the ultra-small Saccharimonadia (phylum CPR/Patescibacteria) suggest a symbiotic lifestyle
(2019-09-01)
The size of bacterial genomes is often associated with organismal metabolic capabilities determining ecological breadth and lifestyle. The recently proposed Candidate Phyla Radiation (CPR)/Patescibacteria encompasses mostly ...
