Article Synopsis
- Rare Earth Elements (REE) found in acid mine drainage (AMD) pose environmental risks, and their capture through Alkaline Passive Treatment Systems (PTS) is the focus of this study.
- Batch experiments were conducted to simulate PTS conditions, using pH adjustments of AMD samples to identify how REE are trapped in secondary mineral phases, particularly between pH 4-6.
- Findings indicate that most REE are associated with aluminum and iron phases, while some light REE are integrated into gypsum through co-precipitation at lower pH, suggesting effective removal strategies in deeper PTS layers.
