Acid Mine Drainage Prediction Acid mine drainage prediction tests are increasingly relied upon to assess the long-term potential of acid generation. This concern has developed because of the lag time at existing mines between waste emplacement and observation of an acid drainage problem (Univ. of California, Berkley ). The issue of. Acid mine drainage (AMD) remediation can be complicated due to its composition, many researchers have used various techniques such as chemical precipitation, solvent extraction, micellar ultrafiltration, organic and inorganic ion exchange and adsorption (Hobbs et al., , De Marco et al., ). The result of high concentrations of metals Cited by: 4. ACID MINE DRAINAGE PREVENTION AND CONTROL OPTIONS Prediction of performance The performance of the designed or selected option(s) compared to the adopted standards is predicted by applying appropriate engineering techniques (e.g., computer modelling). Key engineering considerations would include seepage genera. Acid mine drainage (AMD) has been a detrimental by-product of coal mining for many years. At present, acid mine drainage continues to pose a potential problem in some areas, despite improved prediction and prevention techniques. Acid Mine Drainage Research Acid mine drainage (AMD) has been the subject of intensive research since the 's File Size: 89KB.
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks. Total worldwide liability associated current and future remediation of acid mine drainage (AMD) is approximately , million US-$. Consequences of failing to predict AMD for individual operations and for the mining industry include unplanned spending on remedial measures and reputational damage. Despite these severe risks, predicting AMD properties of mine wastes is typically not an. Investigation of prediction techniques for acid mine drainage. Final Report. Canada Centre for Mineral and Energy Technology, Energy, Mines and Resources Canada, DSS File No 30 SQ. , 61p. At present, acid mine drainage continues to pose a potential problem in some areas, despite improved prediction and prevention techniques. The MDTI was formed as a partnership of technical experts from industry, state and federal agencies and academia who have joined together to combat the pervasive problem of AMD.
This SpringerBrief focuses on Acid Mine Drainage (AMD) in the three basins in the Witwatersrand, South Africa. It provides a background to AMD and its impactsfrom a social science South African government and non-governmental organizations’ response to AMD is assessed, as well the socio-economic and developmental effects of AMD.
