Charac teristics of acid mine drainage of Dexing C opper Mine

This work aim s at the characteristics of acid mine drainage of Dexing Copper Mine On the basis of the results of observation and analysis of samples collected in situ，it is shown that the characteristics of the acid water are high concentrations of some elements，such as iron，sulfur，aluminium，copper and high acidity The results show that the concentrations of iron，aluminium and sulfur are significantly correlated with the acidity of the acid water．
