Preventing acid mine drainage from mine tailings
Mining activity always has high impact on its surroundings, being waste deposition the cause of multiple and complex problems to the environment. One of them is Acid Mine Drainage (AMD), causing acid water percolation through large areas in the mine site. Portugal was a prosper tungsten producer from the beginning of the XX century, having its apogee during World War II. Nowadays there are mill...
متن کاملRecovery of Metals from Acid Mine Drainage
Acid Mine Drainage (AMD) poses a severe pollution problem attributed to current and past mining activities. Low pH, high concentrations of sulphates and various heavy metals makes AMD treatment a major concern because of possible deleterious effects of the effluent on the surroundings. Treatment methods to address AMD focus on neutralizing, stabilizing and removing problem pollutants through va...

AMd is recognized as one of the most serious environmental problem in the mining industry. the problem of acid mine drainage (AMd) has been present since mining activity began thousands of years ago. Mining activity has disrupted the hydrology of mining areas so badly that it is extremely difficult to predict where water would eventually re-emerge. its causes, treatment have become the focus of...
متن کاملAcid 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 کاملHeavy metals from acid mine drainage - impacts and modelling strategies
Mine drainage is increasingly becoming a problem in the UK as water tables rise and acid drainage waters rich in heavy metals impact river systems. The impacts of mine drainage at two sites, the River Pelenna in Wales and the Wheal Jane Mine in Cornwall is assessed. Mathematical models have been developed and applied to investigate heavy metal pollution in the Pelenna case study and the models ...
