Overview

Field deployment of a limestone-based hybrid passive treatment significantly reduces copper and manganese in acid mine drainage, indicating potential ecological benefits.

Key Points

  • Treatment system removed Cu (88.5%) and Mn (66.83%), while increasing pH to 6.26, improving local ecosystem health.
  • A 15-hour hydraulic retention time under both oxic and anoxic conditions was critical for effective treatment in both lab and field settings.
  • The innovative limestone treatment combines leach beds and packed reactors, addressing challenges of abandoned mine sites with ongoing AMD issues.
  • Observations revealed Cu-armoring that may affect the system's long-term performance, suggesting further refinement is necessary.
