| Abstract: | In southern Spain, coal seams typically contain pyrite. The mines there are characteristically contaminated by the presence
of diverse metals disolved in acidic water. An experimental passive system, containing an anoxic limestone draine, organic
matter and wetlands, was constructed to assess how best to inprove the water chemistry. The procedure we used is reported
on here so others can learn from what we did. |
