Sulfate migration and transformation in relation to iron in acid mine drainage:A case study from the waste coal mine area,Zhijin County,Guizhou Province
Sulfate is the main component of acid mine drainage. High-concentration-sulfatewaste water discharged into the environment can produce a series of pollution and ecological dama-ges. We collected the water and sediment samples from a basin affected by acid mine drainage ina karst area of Zhijin County, Guizhou Province and investigated the migration and transformationof sulfate in the steam system.
