Bioleaching of Metal-Polluted Mine Tailings: A Comparative Approach Between Ex Situ Slurry-Phase Stirred Reactors Versus In Situ Electrokinetic Percolation

Applied Sciences
This work compares two technologies for the remediation of metal-polluted mine tailings based on lab-scale bioleaching experiments performed in (a) conventional agitated slurry-phase reactors and (b) in situ electrokinetic percolation.

ияние на негативни педогенни процеси, които протичат в някои почви + подпочви, влошавайки тяхното плодородие и екологичен статус

Почвознание, агрохимия и екология, 2011
Many soil scientists and particularly ecologists do explain the retrogression and degradation of a given landscape with development of certain pedogeno-anthropogenic and anthropogenic processes.
