Water flowing from underground and surface mines and contains high concentrations of dissolved metals is called mine drainage. Mine drainage can be categorized into several basic types by their alkalinity or acidity. Sulfide rich and carbonate poor materials are expected to produce acidic drainage, and alkaline rich materials, even with significant sulfide concentrations, often produce net alkaline water.
Mine drainages are dangerous because pollutants may decompose in the environment. In certain conditions metals can be concentrated in environmental, and by others can be dispersed.
Two methods can treat mine drainage to eliminate or reduce contamination by acidity and heavy metals. The active treatment method uses alkaline chemicals to neutralize acid-polluted water. However, the chemicals are expensive and the treatment facility is expensive to construct and operate. The passive treatment method uses a treatment system that employs naturally occurring chemical and biological reactions to treat mine drainage with little maintenance.
In this paper mine drainage treatments are presented.
