Assessment of acid-sulfate drainage in an environmental liability associated with an ancient sulfuric acid industry in a sector of the Río de la Plata coastal plain: Impacts on soil and water quality
(Springer, 2021-04)
Environmental liabilities have become one of the most important problems at environmental level, especially those located in urban areas. Within the area of the Río de la Plata coastal plain, industrial waste abandoned by ...
Performance of a sulfidogenic bioreactor inoculated with indigenous acidic communities for treating an extremely acidic mine water
(Facultad de Ingeniería y Tecnología, 2019)
Mining contributes to water pollution through the generation and uncontrolled release of sulfuric acid and metalliferous drainage (AMD). While sulfate reducing bacteria have been used for the bioremediation of AMD, one of ...
Rapid and specific detection of Acidithiobacillus ferrooxidans and Leptospirillum ferrooxidans by PCR
(ELSEVIER, 2008-06)
Acidithiobacillus ferrooxidans and Leptospirillum ferrooxidans are two of the most important bacteria in heap bioleaching processes of copper sulphide at common operating temperatures (18-24 degrees C). In this paper, both ...
Assessment of a UASB reactor for the removal of sulfate from acid mine water
(ELSEVIER SCI LTDOXFORD, 2012)
A bench-scale Upflow Anaerobic Sludge Blanket (UASB) reactor was used to study the treatment of acid mine drainage through the biological reduction of sulfate. The reactor was fed with acid mine drainage collected at the ...
A kinetics analysis applied to the recovery of Zn(II) content from mine drainage by using a surfactant liquid membrane
(Taylor and Francis Inc., 2010)
A kinetics analysis was conducted for the recovery of zinc (II) ions from a mine drainage sample by a liquid surfactant membrane containing di-(2-ethylhexyl)phosphoric acid as a carrier extractant and Span-80 as the ...
Radionuclides (222Rn, 226Ra, 234U, and 238U) Release in Natural Waters Affected by Coal Mining Activities in Southern Brazil
(2017-01-01)
Water quality was evaluated in a coal mining area in the city of Figueira, Paraná State, Brazil, where uranium was associated with the coal deposit. Upstream the mine, groundwaters were more acid and some elements and ...
Application of horizontal-flow anaerobic immobilized biomass reactor for bioremediation of acid mine drainage
(2016-06-01)
The production of low-pH effluent with sulfate and metals is one of the biggest environmental concerns in the mining industry. The biological process for sulfate reduction has the potential to become a low-cost solution ...
