Removal of Iron and Sulphates from Acid Mine Drainage and Neutralisation of pH Using Chemical Process
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 9
Abstract
Acid mine drainage refers to the outflow of acidic water from a mining site. A significant number of coal mines suffer from acid mine drainage. It is a worldwide problem, leading to ecological destruction in watersheds and the contamination of human water sources. The increased acidity caused by acid mine drainage has a range of negative effects depending on the severity of the pH change. AMD ia normally having high amounts of sulphur and iron also. Limestone, dolomite and slag have been tried for the removal of iron and sulphates from acid mine drainage water. It has been found that these chemicals can be successfully used for the removal of iron and sulphates and to neutralise the pH of acid mine drainage water.
