Summary
Acid drainage is a persistent environmental problem in many mineralized areas. The drainage results from weathering of sulfide minerals that oxidize to produce hydrogen ions and contribute dissolved metals to solution, posing a considerable threat to the environment. In this chapter we construct geochemical models to consider how the availability of atmospheric oxygen and the buffering of host rocks affect the pH and composition of acid drainage. We then look at processes that can attenuate the dissolved metal content of drainage waters.
