Acid-mine drainage (AMD) is difficult and costly to treat. We investigated a new approach to AMD treatment using fuel cell technologies to generate electricity while removing iron from the water. Utilizing a recently developed microbial fuel cell architecture, we developed an acid-mine drainage fuel cell (AMD-FC) capable of abiotic electricity generation.

The essence of this test was to determine the scope to neutralize flotation ,wastewater, by ,acid mine, drainage. As presented above, the flotation ,wastewater, had a high pH of ~12, and AMD had a low pH of ~3, while the water discharged into the river should have a pH of 7–8. Thus, ,acid mine, waters were used to neutralize alkaline flotation ,wastewater,.
