Book excerpt: With conventional acid mine drainage remediation consisting of acid neutralization and metal sedimentation, operation and maintenance costs can be overwhelming. If the sludge, primarily iron oxide in southeastern Ohio, is effectively processed, it can be utilized as an industrial grade pigment. At many locations, however the iron content in the sludge may be below standards due to aluminum contamination. In this work, we tested precipitating iron at low pH with the aid of acidophilic iron- oxidizing bacteria to produce a pure pigment. Using acid mine drainage from seeps in southeastern Ohio, at a range of pHs and inoculated with a local bacterial consortium, metal precipitate was produced and analyzed.
