AMD from Sulfide Mines

AMD, or Acid Mine Drainage, occurs when sulfide minerals in mining waste react with water and oxygen, producing sulfuric acid. This acidic water can leach heavy metals from surrounding rocks, leading to environmental contamination of nearby streams and soil. It is a common issue in sulfide mines, especially when waste materials are exposed to weathering. AMD can harm aquatic life, disrupt ecosystems, and pose risks to human health. Managing AMD involves covering waste piles, neutralizing acids, and treating contaminated water to reduce environmental impacts from mining activities.
