Heavy 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 ...
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...
متن کاملIon exchange system design for removal of heavy metals from acid mine drainage wastewater
This paper discusses the methodology used to determine the optimal ion-exchange column size to process all separate batches of feeds from acid mine drainage wastewater. The optimal design ensures the best utilization of resin material and therefore results in a minimum amount of spent resins. Ion exchanger materials have been studied for removing heavy metals from a metal bearing wastes. For th...

متن کاملHeavy Metals from Acid Mine Drainage in Coal Mines-A Case Study
Acid drainage is most common problem or associated with almost all mines containing sulphide deposits and coal containing high pyrite. Acid drainage is caused when rain water and or seepage from rock formation interact with sulphur bearing minerals. It produces water of high acidity with higher metal concentration. Acid drainage is most susceptible to dissolve heavy metals particularly Iron, Zi...
