Closed-loop mining waste management: modification of clay byproducts for recovery of heavy metals from acid mine drainage

Key Points

• Recovery of heavy metals was enhanced through the modification of clay byproducts, improving waste management practices.
• The analysis showed a significant reduction in heavy metal levels from acid mine drainage, indicating a 30% improvement over unmodified methods.
• This research utilized closed-loop mining techniques to modify clay byproducts for better absorption in polluted water systems.
• The findings highlight the potential for innovative waste management solutions, with broader applications in mining and environmental cleanup.
