Microbial communities in pyritic tailings actively influenced water chemistry during a 36-week weathering test. Both aerobic and anaerobic bacteria demonstrated significant metabolic activity, impacting the final water quality.

Area of Science:

  • Environmental Microbiology
  • Geochemistry
  • Biogeochemical Cycles

Background:

  • Pyritic tailings pose environmental risks due to potential acid mine drainage.
  • Understanding microbial roles in tailing weathering is crucial for remediation strategies.

Purpose of the Study:

  • To assess the metabolic activity of microbial populations in pyritic tailings.
  • To investigate the distribution and activity of bacteria during a simulated weathering process.

Main Methods:

  • A 150cm column packed with pyritic tailings (63.4% pyrite) was subjected to distilled water percolation for 36 weeks.
  • Chemical and microbiological analyses were performed on collected water and tailing samples.
  • Selective isolation and activity testing of aerobic and anaerobic bacteria were conducted.

Main Results:

  • Microbial life was selectively distributed within the column, with aerobic sulfur- and iron-oxidizing bacteria in oxygenated zones and anaerobic sulfur-reducing bacteria in anoxic zones.
  • Both oxidizing and reducing bacterial populations remained metabolically active throughout the 36-week test.
  • The water draining from the column showed chemical changes resulting from biological oxidation and reduction processes.

Conclusions:

  • Microbial consortia play a significant role in the biogeochemical transformations within pyritic tailings.
  • The metabolic activity of these microbes directly influences the quality of drainage water.
  • These findings highlight the importance of microbial processes in tailing weathering and acid mine drainage formation.
