摘要：

One of the major impacts caused by coal mining activity is water pollution from acid mine drainage (AMD). AMD is produced by the reaction of pyrite, water and oxygen, that is intensified in the acidophilic bacteria presence. This solution acts as a leaching agent of minerals present in the residue, producing a solution with dissolved metals and sulphuric acid. Conventional treatment of AMD consists of neutralization and precipitation of heavy metals, but is technically deficient. The electrodialysis (ED) has emerged as an attractive process for effluents treatment since it does not need reagents addition and generates no waste polluting in the environment. The ED used to treat the AMD is a membrane process that consists in the separation of cations and anions by the application of an electric field on a process cell. In this study the possibility of using ED to the AMD treatment was evaluated aiming water reuse.
