Metal sulphates are one of the major contributors to acid mine drainage (AMD) or acid rock
drainage (ARD). AMD occurs by the oxidation of metal sulphides. Sulphides produce …

Groundwater contamination with heavy metal (loid) s occurs worldwide. Permeable reactive
barriers (PRBs) have been widely accepted as an alternative to traditional ex-situ removal …

Water is needed at mine sites for dust suppression, mineral processing, coal washing, and
hydrometallurgical extraction. For these applications, water is mined from surface water …

As an emerging new class of materials comprising two different metals, bimetallic
nanoparticles (NPs) exhibit new functions because of the synergistic rather than merely …

This study provides a comprehensive review of the permeable reactive barrier (PRB)
technique for groundwater remediation for a wide range of contaminants. We have …

Applications of zerovalent iron (ZVI) for water treatment under aerobic conditions include
sequestration of metals (eg, in acid mine drainage) and decolorization of dyes (in …

In order to treat acid mine drainage (AMD) effectively using sulfate-reducing bacteria (SRB)
at high concentration of sulfate and heavy metals, Fe0 was added to enhance the activity of …

Mineralogical, geochemical and microbial characterization of tailings solids from the Greens
Creek Mine, Juneau, Alaska, was performed to evaluate mechanisms controlling aqueous …

Sulfidogenic biochemical reactors (BCRs) for metal removal that use complex organic
carbon have been shown to be effective in laboratory studies, but their performance in the …

Acid mine drainage and the associated contaminants, including As and metals, are ongoing
environmental issues. Passive remediation technologies have the potential to remove As …
