Acid Mine Drainage Prevention and Control Options
Acid mine drainage (AMD) is one of most significant environmental challenges facing the mining industry worldwide. It occurs as a result of natural oxidation of sulphide minerals contained in mining wastes at operating and closed/decommissioned mine sites. AMD may adversely impact the surface water and groundwater quality and land use due to its typical low pH, high acidity and elevated concent...
متن کاملAdvances in Acid Rock Drainage (ard) Characterisation of Mine Wastes
Research was carried out to improve acid rock drainage (ARD) prediction methodologies, focussing on resolving uncertainties in acid base accounting (ABA) methods. Advancements, their application, and interpretation are reported. Consideration of both net acid production potential (NAPP) and net acid generation (NAG) test results provide a more reliable routine screening technique than either te...
متن کاملPrediction of Acid Mine Drainage Potential of Geothermal Solid Wastes
Geothermal solid wastes such as scale and sludge from the Philippines and Mexico containing Cu, Zn, and Pb at levels above earth's crustal abundance were studied for their acidification potential if disposed in a landfill. A batch reactor technique using the iron and sulfur oxidizing bacteria ThiobaciZlus ferrooxidans was developed for geothermal wastes to predict their acid mine drainage and b...
متن کاملPrediction of Acid Mine Drainage Generation Potential of A Copper Mine Tailings Using Gene Expression Programming-A Case Study
This work presents a quantitative predicting likely acid mine drainage (AMD) generation process throughout tailing particles resulting from the Sarcheshmeh copper mine in the south of Iran. Indeed, four predictive relationships for the remaining pyrite fraction, remaining chalcopyrite fraction, sulfate concentration, and pH have been suggested by applying the gene expression programming (GEP) a...
متن کاملBio-Remediation of Acid Mine Drainage in the Sarcheshmeh Porphyry Copper Mine by Fungi: Batch and Fixed Bed Process
Acid mine drainage (AMD) containing high concentrations of iron and sulphate, low pH and variableconcentrations of heavy metals leads to many environmental problems. The concentrations of Cu and Mnare high in the AMD of the Sarcheshmeh porphyry copper mine, Kerman province, south of Iran. In thisstudy, the bio-remediation of Cu and Mn ions from acid mine drainage was investigated using two nati...
