R600 million per annum has been committed to creating a permanent solution to acid mine drainage that will also produce potable water. The purpose of the long-term solution is to further treat the water by removing the sulphates and creating water for commercial use as either industrial or potable water.
Constructed Wetlands for Treating Acid Mine Drainage. By Kathryn Smith . Introduction . The mining industry has felt the burden of both negative environmental criticism and strong governmental regulations. In the past mineral extraction and processing has been a source of many contaminants entering our water soil and air.
Where Acid Mine Drainage Happens . It mostly occurs where mining is done to extract coal or metals from sulfur-bearing rocks. Silver gold copper zinc and lead are commonly found in association
According to the U.S. Geological Survey the ongoing issue of acid mine drainage is contaminating more than 3000 miles of the commonwealth’s streams subduing ecosystems and costing roughly $67
Diverting water from the mine site to prevent it from running through AMD-forming materials. Disposing mine waste underwater to prevent exposure to oxygen. In addition to the methods listed above a wide variety of alternative methods have been employed to prevent or treat acid mine drainage.

methods which prevent the formation of acid mine drainage would be preferable. Recent studies with Appalachian coal refuse types have indi ed that certain types of alkaline amendments have the potential to prevent acid mine drainage from pyritic coal refuse. This paper discusses a research project in which kiln dust Fluidized Bed Combustion
Encapsulation is a typical method used to prevent potential acid mine drainage AMD in overburden piles. In this method Potentially Acid-Forming PAF material is covered with either Non-Acid
The combination of exothermic acid mine drainage reactions and the insulating properties of the plastic liner and soil cover typically prevent freezing although in extreme cold climates additional insulation may be required.
Pyrite oxidation which can lead to acid mine drainage is a concern for miners all across the globe. However little is known about the processes that cause this phenomenon.
AMD is one of the critical environmental problems that causes acidifi ion and metal contamination of surface and ground water bodies when mine materials and/or over burden-containing metal sulfides are exposed to oxidizing conditions. The best option to limit AMD is early avoidance of sulfide oxidation.

Preventive and corrective techniques of acid mine drainage Preventive techniques are those whose objective is to prevent the production of acid effluents from the mine. On the other hand corrective techniques are designed to treat the acidic waters produced by mining so that they stop being a threat to the environment.

Acid mine drainage control can be undertaken where AMD exists or is anticipated. Control methods treat the acid-producing rock directly and stop or retard the production of acidity. Treatment methods add chemicals directly to acidic water exiting the rock mass.
Treatment of AMD: Acid mine drainage sometimes forms when certain minerals in the soil and rocks around mines are exposed to weathering processes during mining. These exposed minerals release their contents into creeks causing them to become acidic. This kind of pollution damages aquatic life and makes the water useless or harmful for others
Coating of certain mine wastes has been also investiga ted as an alternative method to prevent pyrite oxidation. The mechanism of coating involves the leaching of mining waste w1th a phosphate solution containing hydrogen peroxide.
