Acid mine drainage remediation options: a review

Feb 01, 2005· Acid mine drainage (AMD) causes environmental pollution that affects many countries having historic or current mining industries. Preventing the formation or the migration of AMD from its source is generally considered to be the preferable option, although this is not feasible in many locations, and in such cases, it is necessary to collect, treat, and discharge mine water.

What can be done to prevent or clean up acid mine drainage

Water flowing through active or abandoned mine sites can become polluted by the material being mined[1]. By far the most common mine drainage problem is that of acid mine drainage (AMD). Sulfuric acid is produced when water interacts with sulfur-bearing materials in the presence of oxygen and common bacteria[1]. The acidic water formed by this process can dissolve many metals in bioavailable
