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 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 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 کاملHeavy metal removal mechanism of acid mine drainage in wetlands: A critical review
Acid mine drainage (AMD) is one of the most significant environmental challenges facing the mining industry worldwide. Water infiltrating through the metal sulphide minerals, effluents of mineral processing plants and seepage from tailing dams becomes acidic and this acidic nature of the solution allows the metals to be transported in their most soluble form. The conventional treatment technolo...
