ACID MINE DRAINAGE (AMD) CONTAMINATION IN COAL MINES AND THE NEED FOR EXTENSIVE PREDICTION AND REMEDIATION: A REVIEW

Acid mine drainage (AMD) contamination in coal mines and the need for extensive prediction and remediation: a review

Globally, the major source of environmental pollution as a result of mineral End Cap Handlebar exploitation and processing is acid mine drainage (AMD).AMD refers to outflowing streams of acidic constituents from pyrite-bearing ore mines.The exposure of pyrite (FeS2) in coal waste dumps to atmospheric oxygen and water in the presence of microbial co
